Isn t the chemical fiber an insulator, why does it cause friction electricity?

Although chemical fiber is an insulator, 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 object gains excess electrons.

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 nucleus and transfer to another object, so that the number of negative charges in the electron belt outside the nucleus changes. When an object loses electrons, it shows being positively charged when the total number of negative charges in its electron band is less than the positive charge of the nucleus;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.

Chemical fiber is indeed an insulator, but when you are dressed, after the chemical fiber rubs against the body, the chemical fiber will have negative electrons on it, and then it will attract each other to the dust, which is the same as frictional electricity.

No, I've already passed this question in your question, but you can't see the obvious signs of conductor friction electrolysis, in fact, the starting point of friction is possible.

The essence of triboelectric induction is the transfer of charge between different objects, your charge is transferred between insulators, because insulators do not conduct electricity, the charge will remain on the friction surface of the insulator, and obvious charging phenomena can be observed;If it is a conductor, even if there is charge transfer in friction, the transferred charge will be evenly distributed throughout the conductor and it is not easy to observe the phenomenon, especially when the conductor is connected to the earth in a certain way (such as the human body), it will quickly transfer the charge to the earth, not to mention what charged Wu Changhui elephant.

In fact, there is no very strict boundary between the conductor and the insulator, and the insulator can also become a guide cavity answering body under certain conditions.

Hope mine can be helpful to you.

Who says you can't? On the contrary, most of the triboelectric we generally talk about occurs on insulators, such as: wooden combs, glass rods, fur, etc., which are all insulators.

This is not to say that only insulators produce friction starters. The essence of triboelectric induction is the transfer of charge between different objects, your charge is transferred between insulators, because insulators do not conduct electricity, the charge will remain on the friction surface of the insulator, and obvious charging phenomena can be observed;In the case of a conductor, even if there is charge transfer in friction, the transferred charge will be evenly distributed throughout the conductor and it is not easy to observe the phenomenon, especially when the conductor is connected to the earth in some way (such as the human body), it will quickly transfer the charge to the earth, not to mention any charged phenomenon.

In fact, there is no strict boundary between conductors and insulators, and insulators can become conductors under certain conditions.

Hope mine can be helpful to you.

No, if you can, it's not an insulator.

Science experiments that can be done at home allow children to learn science while playing.
