1. Features of intelligent materials: Intelligent materials refer to materials that can sense changes in external environment or internal state, and can change their performance parameters in real time and make appropriate responses through their own information processing and feedback mechanisms to adapt to the ever-changing environment.

The idea of intelligent materials comes from bionics, and its goal is to develop a material and make it a "living" material with various functions similar to those of living things. Therefore, intelligent materials must have three basic elements: perception, driving and control. For example, some sunglasses have smart materials that sense the surrounding light and can judge the intensity of light. When the light is strong, it will dim; When the light is weak, it becomes transparent. If smart materials are applied to interior design, it will bring good news to users.

Specifically, smart materials may have the following characteristics: sensing function; Information identification and accumulation function; Response function; Self-diagnosis ability; Self-repair ability; Self-regulation ability.

2. A new intelligent material: (1) nanocomposites.

Nano-material is a kind of environmental protection material, which is the product of making individual atoms and molecules into specific functions according to human will. Nanotechnology is a new technology developed rapidly in the early 1990s. Nano-materials have made great contributions to the improvement of coatings, ceramics, cement and other products. Nano-materials have broad prospects in solving the brittleness problem of ceramic materials, improving the application value of ceramic materials, and manufacturing optical functional materials, refrigeration materials and coating materials with various functions. For example, when processed in ceramics, nano-aluminum chloride can play a significant role in strengthening and toughening.

(2) Antireflective glass

The light reflectivity of the glass surface is 4%, which can be reduced by coating the glass surface. A better antireflection film can reduce the reflectivity of glass from 8% to 2% ~ 3%. The main advantage of antireflection glass is to eliminate or reduce the visual instability caused by light reflection, making the glass more transparent and non-reflective. Anti reflective glass is often used in windows and other parts to make people's vision stable, and objects in the glass are not disturbed by reflected light at any angle. Anti reflective glass can be used in museums, libraries, shops, various glass barriers and various viewing windows in public places.

(3) Self-cleaning glass

In 2004, Japan newly developed architectural glass with self-cleaning function, which was coated with a photocatalytic degradation film, which could be degraded in the sun. Due to the increasingly serious industrial pollution, various pollutants in the atmosphere are beyond the natural degradation ability, such as carbon oxides and nitrogen oxides, 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, some organic pollutants and some microorganisms such as bacteria in the surrounding environment. Dust and other dirt on the glass surface can be thrown away by itself, so it is named self-cleaning.
