PMMA has a good light diffusion effect, we should research PMMA material stratifily. There are four aspects of research to proceed: (1)Focus on the mutual tolerance of matrix resin and scatterer particles to improve the effect of light scattering. (2) Careful analysis of what factors affect the light diffuser function; in the light diffusion material and further strengthen the effect of light scattering of PMMA. (3)Pay attention to the connection to polymerization method preparation, and vigorously develop application and performance of polymerization method. (4)By subtle observation on the PMMA diffuser material and analysis and research of physical performance,improve the performance PMMA diffuser material further.
