What are organic smart materials What are the organic smart materials

<>1. Characteristics of intelligent materials: intelligent materials refer to a class of materials that can perceive changes in the external environment or internal state, and can change the performance parameters of the material itself in real time through its own information processing and feedback mechanism, make appropriate responses, and adapt to the changing environment.

The idea of smart materials is based on biomimicry, and its goal is to develop a material that becomes a "living thing" with various functions similar to that of living organisms"materials. Therefore, smart materials must have three essential elements: perception, actuation, and control. For example, some sunglasses have smart materials that sense the light around them, which can judge the intensity of the light, and when the light is strong, it will be darkened; When the light is low, it becomes transparent.

If smart materials are applied to interior design, it will bring good news to users.

Specifically, smart materials may have several characteristics: sensing capabilities; information identification and accumulation function; responsive features; self-diagnosis capability; self-healing ability; Self-regulating capability.

2. New smart materials: (1) nanocomposites.

Nanomaterials are a kind of environmentally friendly materials, and they are products that can be manufactured by human beings to produce specific functions from individual atoms and molecules according to their own will. Nanotechnology is an emerging technology that developed rapidly in the early 90s of the 20th century. Nanomaterials have made great contributions to the improvement of coatings, ceramics, cement and other products.

Nanomaterials have broad prospects in solving the brittleness problem of ceramic materials, improving the application value of ceramic materials, making optical functional materials, refrigeration materials and coating materials for various functions. For example, nano aluminum chloride processing in ceramics can significantly enhance and toughen the role.

2) Anti-reflective glass.

The light reflectivity of the glass surface is 4, and the reflectivity can be reduced by coating the glass surface, and the better anti-reflective film can reduce the reflectivity of the glass from 8 to 2 3. The main advantage of anti-reflective glass is that it eliminates or alleviates the visual instability caused by light reflection, making the glass more transparent without reflection. Anti-reflective glass is often used in parts such as shop windows, so that people's vision is stable, and objects in the glass are not disturbed by reflected light when viewed at any angle.

In construction projects, anti-reflective glass can be used in museums, libraries, shops, public places of various glass barriers and various viewing windows.

3) Self-cleaning glass.

In 2004, Japan newly developed a new architectural glass with self-cleaning function, and coated a photocatalytic degradation film on the surface of the glass, which can undergo degradation reaction under sunlight. Due to the increasingly serious industrial pollution, various pollutants in the atmosphere exceed the ability of natural degradation, such as the content of various carbon oxides and nitrogen oxides in the spring is getting higher and higher, and the development of materials to degrade these pollutants has also become the research content of ecological building materials. Self-cleaning glass can degrade pollutants in the atmosphere, also have a degradation effect on some organic pollutants, and also have a certain inhibitory effect on bacteria and other microorganisms in the surrounding environment.

Dust and other dirt contaminated on the surface of the glass can be thrown away on its own, hence the name self-cleaning.

Some sunglasses contain smart materials that sense the light around them and can judge the intensity of the light, which becomes dark when the light is strong and transparent when the light is weak.

Intelligent materials, also known as smart materials, are a new sub-discipline of materials that developed rapidly in the 90s of the 20th century. This material often combines high-tech sensors or sensitive components with traditional structural and functional materials to give the material new properties, making the inanimate material seem to have a "feeling" and "perception", and have the function of self-perception and self-healing.
