Abstract

The invention relates to a polymer-based composite structure diffuse reflection material. The material is characterized in that: the diffuse reflection material, which is formed by multi-layer structures, comprises a microstructure surface layer material, a single layer or multi-layer intermediate material and a reflecting layer material. Specifically, the surface microstructure is a microlens array having a linear or non-linear geometrical characteristic; and the surface microstructure is in a microgroove type, a ball type, an ellipsoid type, a polygonal type, a paraboloidal type, a hyperboloidal type or a combined type. According to the invention, the prepared diffuse reflection high polymer material with the composite structure has advantages of high reflectivity and good diffuse reflection effect.

Description

Technical field:

[0001] Polymer matrix composites, polymer material processing, micro-nano manufacturing. Background technique:

[0002] With the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for environmental comfort. At present, most of the reflective materials used are aluminum, copper, nickel, chromium and other metal materials or metal-plated plastic surfaces. In this case, if the light source is a point light source, this reflective material will form a specular reflection, which is prone to problems such as glare and uneven illumination. Moreover, the oxidation of the metal material will also reduce the reflection efficiency. As a new type of light source, LED is currently widely used in various fields, including display and various lighting occasions. Compared with ordinary light sources, white light LEDs for lighting are characterized by their small size but ultra-high brightness and direct...
