The main function of the light diffusion film is to modulate the light intensity of the incident beam in space, that is through the reflection, scattering, refraction and diffraction of the light and the diffusion film, the diffused light field distribution that meets the requirements of a certain application can be obtained.

Light diffusion polycarbonate (PC) can significantly improve the lighting effect of light emitting diode (LED) lighting. Two kinds of photodiffused PC materials were prepared by using acrylic and organosilicon photodiffusive particles. The dispersibility and light diffusivity of PC materials were studied by scanning electron microscope (SEM), light transmittance test and thermal property analysis.

The performance and characteristics of polytetrafluoroethylene, the common methods of modi- fying polytetrafluoroethylene and polymer alloys, and the application of polytetrafluoroethylene in the fields of electronics, electrical, medical and environmental protection are introduced.

Polycarbonate(PC) was used as matrix material，acrylic and organosilicone resins were used as light diffusing agents，the effect of the type，contents and particle size of light scattering agents on the mechanical properties，transmittance and haze of light diffusing materials based on PC were studied.

Through the performance difference analysis of various water soluble lm former resin in the process of trial production and application results of various light diffusion additives in coating, selection and application researches of the lm formers resin and light diffusion additives are carried out on light diffusion coating of the linear glass tube LED lamp .

Silicone resin powder is also suitable for high-end anti-adhesive film with high transparency and shedding resistance, which can be produced by two-way stretching method.
