Abstrakt: In this study, a thermal conductive light diffusion material with good optical and thermal conduction was prepared by blending polystyrene (PS) and magnesium hydroxide (MH) as an inorganic filler to match the refractive index. The comprehensive performance of the PS/MH thermal conductive light diffusion materials were regulated through adjusting the content of MH and employing the MH with a multi-particle size for compounding based on the experimental results obtained from the measurements on their micro-morphology, optical properties, thermal conductivity and mechanical properties. The results indicated that there was an MH thermal conductivity network formed in the matrix with an increase in the MH content. The transmittance of the thermal conductive light diffusion materials decreased gradually, their haze increased and tended to be stable, and their thermal conductivity was significantly improved. When 30 wt% MH with a multi-particle size content was incorporated, the resultant PS-30-3 thermal conductive light diffusion material obtained optimal comprehensive performance, its transmittance and haze reached 75. 9 % and 92. 70 %, respectively, and its thermal conductivity reached 0. 52 W/(m·K), which is 10 times as much as that of pure PS [0. 05 W/(m·K)].
