What does triboelectric mean and what is triboelectric induction

Electrification by friction is the transfer of electrons from one object to another, causing the two objects to be charged by an equal amount. The object that gains electrons is negatively charged, and the object that loses electrons is positively charged. Therefore, when two uncharged objects are electrorically charged by friction, the amount of electricity they carry must be equal numerically.

Objects that have been rubbed have the phenomenon of attracting small and light objects.

Two Charges: There are only two types of charges that exist in nature. It is stipulated that the charge of the glass rod that has been rubbed by silk is called positive charge, and the charge of the rubber rod that has been rubbed with fur is called negative charge.

Interaction between charges: Charges of the same species repel each other, and charges of different species attract each other.

Any two objects rubbing against each other can be electrified. In the mid-18th century, the American scientist Benjamin Franklin analyzed and researched that there are two kinds of electricity with different properties, called positive electricity and negative electricity. The electricity carried by an object due to friction is either positive or negative.

Substance: The essence of triboelectric power is the transfer of electric charge.

After friction, the charge of the object is transferred, resulting in positive and negative charges in some objects.

Charges are exchanged by friction, and the electrical properties of the charged body are determined according to the microscopic chemical structure.

Electrifying an object by friction is called triboelectric charging.

The phenomenon of using friction to make an object pointed.

The object is electrified by the method of friction.

The friction of any two insulators can produce an electric field, which is often referred to as static electricity. Since the insulator does not have a venting path, the electric field will become higher and higher, and when the insulator finds a path with a lower resistance, the electric field accumulated by the insulator itself will be discharged to it. Although a human being is also a conductor due to the water contained in the body, the stratum corneum of the human being has a great electrical resistance, and the human being is not a good conductor.

In addition, people basically wear cloth shoes, rubber-soled shoes, leather soles or plastic-soled shoes with high insulation rate, and they are basically in an insulating state for the earth. When a person walks in a turbulent airflow and wears chemical fiber clothes with a high insulation rate, if the shoes on his feet are low with a high insulation rate, the static electricity on the person's body will slowly increase. When the voltage is high enough to a certain extent, it will leak outward.

Due to the relative other organs, the fingers are the most pointed and thin; The high-voltage electric field has the characteristics of tip discharge, so when people encounter tip discharge, they basically start from the tip of the finger. That's why people thought his hands were static. In fact, the static electricity on the human body is discharged through the hands.

What is the cause of triboelectric electricity.

Objects rubbing against each other, the energy of frictional motion is transferred to the outer electrons in the atoms of one of the substances, so that it has the force to break away from the nucleus and transfer to another substance, if it is maintained, the collision of the excess electrons obtained is convenient to carry a negative charge (excess electrons), and the other side is positively charged because of the loss of electrons; This is known as triboelectric induction.

What is the result of triboelectric activation? _?

The charge of the glass rod that is rubbed against the pin with laughter is positive, and the charge of the rubber rod that is rubbed with fur is negative.

What are the conditions for triboelectric activation?

Take your time.

No, some are induction-electrified.

Induced electricity is the phenomenon of redistribution of the charge of an object under the action of an electrostatic field. For example, in the process of powering up a device, a certain electromagnetic field is generated, and the peripheral objects will be affected by the field to induce some charges, such as the screen of the display is electrified.

The capacitive electrification is more complicated, because the charged body that already has a certain charge is close to and separated from the cavity excitation of another substance. According to the parallel plate capacitance formula c = s 4 kd (s is the area directly opposite the metal sheet, d is the distance between the two metal sheets). When the capacitance of the system changes, it can be seen from the nuclear socks Q=CV (C is the capacitance, V is the voltage) that the electrostatic potential on the object or the human body carrying a certain amount of electricity will change, which will lead to the damage of microelectronic devices such as manifolds.

I hope I can help you with your doubts.

Theoretically, it is.

When different substances rub against each other, those with strong ability to bind electrons are easy to get electrons, and those with strong ability to bind electrons are easy to lose electrons, lack electrons and become positively charged.

It's just that some objects, such as metal, will be carried away or dispersed to the entire metal body after being charged by friction, and there is almost no electricity to the outside.

Triboelectric initiation is only one type of electropowering method, and there are also induction energizing and contact energizing.

When two objects rub against each other, the object with strong ability to bind electrons outside the nucleus gets electrons and is negatively charged. The nucleus loses electrons to objects with weak electron binding ability outside the nucleus and becomes positively charged. The essence of triboelectric induction is that the electrons are transferred, not that the charge is created by the bending of the key.

Modern science tells us that any object is made up of atoms, and atoms are composed of positively charged nuclei and negatively charged electrons, and electrons move around the nucleus. Under normal circumstances, the number of positive charges in the nucleus band is equal to the number of negative charges in the electron band outside the nucleus, and the atom is not electrically charged, so the whole object is neutral.

It is difficult to change the number of positive charges in the nucleus, but the electrons outside the nucleus can get rid of the shackles of the nucleus and transfer to another object, so that the number of negative charges in the electron band outside the nucleus changes. When an object loses electrons, the total negative charge of its electron band is less than the positive charge of the nucleus, and the defeat shows that it is positively charged; On the contrary, an object that would otherwise be neutral, when it gets electrons, it shows being negatively charged.

When two objects rub against each other, because the nuclei of different objects have different abilities to bind electrons outside the nucleus, one of them must lose some electrons and the other gain excess electrons.

If a glass rod is rubbed against silk, some of the electrons of the glass rod are transferred to the silk, and the glass rod is positively charged due to the loss of electrons, and the silk is negatively charged due to the electrons it gets. Rub the rubber rod against the fur, some of the electrons of the fur are transferred to the rubber rod, the fur belt is positively charged, and the rubber rod carries the same amount of negative electricity.

Triboelectric Initiation: The frictional object has the phenomenon of attracting small and light objects, which is the phenomenon of triboelectric electrogeny.

Causes, essence and results of triboelectric induction:

Due to the different binding ability of the nucleus of different substances to the electrons outside the nucleus, when two objects rub against each other, which object knows that the nucleus of the ruler body has a weak ability to bind the electrons outside the nucleus, some of its electrons will be transferred to another object, the object that loses the electron is positively charged, and the object that gets the electron is negatively charged due to the excess electron.

Triboelectric is not essentially the creation of electricity, but the transfer of charge from one object to another, so that the positive and negative charges are parted and the total amount of charge does not change. Two objects rubbing against each other must have an equal amount of dissimilar charge, the positively charged object lacks electrons, and the negatively charged object has the same amount of excess electrons.

The height of the code can only transfer electrons outside the nucleus during the transfer process, and the nucleus is stable.

The essence of triboelectric induction: the positive and negative charges are separated, and the transfer of the charge occurs, but the charge is not created.

In the process of triboelectric activation, electrons are obtained by those with strong ability to adsorb (bind) electrons, and electrons are lost with weak ability to adsorb (bind) electrons. And the greater the difference in the strength of the electron ability of the adsorption of Linglu (binding), the easier it is to generate electricity after friction.

The electrons outside the nucleus, which were originally negatively charged, were firmly bound to the positively charged nucleus due to "the same charges repel each other and the different charges attract each other", and the object is electrically neutral.

Similar to tug-of-war, when two objects rub against each other, due to the difference in the ability of the nuclei of different substances to adsorb (bind) electrons, nucleus A with strong electron adsorption (binding) ability will snatch the electrons from nucleus B with weak electron adsorption (binding) ability.

As a result, the number of electrons around nucleus A becomes more and more negative; The electrons around nucleus B become less ripe and appear positively charged. This is called triboelectric induction, which uses the method of friction to electrify an object.

It is impossible for two imitation objects of the same substance to rub against each other.
