摘要
本研究利用分散聚合法成功的合成出窄粒徑分佈的實心微粒子，其分別為2.76、9.25μm的PS微粒子、2.26μm的PSM-AN微粒子、以及改質過後的PSM-ANOH微粒子，此外還以AIBN及SLS-SFS兩種種子聚合法製備出2.76μm的PDVB、PDVB-GMA多孔微粒子。
再將這些微粒子與水性樹脂混合而製備出不同條件的光擴散膜，並量測其性質，由結果中得知當基材樹脂與高分子微粒子間的界面面積愈大或是折射率差愈大時會得到較佳的散射率。AIBN系統所做的多孔微粒子由於有很大的表面積所以屬於高散射率而低全光穿透率型的擴散劑；SLS-SFS系統所做的微粒子則偏向中空的型態，因而在散射率及全光穿透率方面都有不錯的效果。

In this study, uniformly solid-centred microspheres are prepared by using dispersion polymerization, including PS particles with 2.76μm and 9.25μm, PSM-AN particles with 2.26μm, PSM-ANOH particles with 2.26μm. Besides, we also use seed polymerizations with two different initiators of AIBN and SLS-SFS to synthesis porous particles, including PDVB porous particles with 2.76μm , PDVB-GMA porous particles with 2.76μm.
The different light diffuser films are prepared via coating the mixture which contained various kinds of polymer particles and acrylate resin. In addition,the optical properties are tested with these. The results show that the diffusion ration will increase with the increasing of the total surface areas and of the differences of refractive index between the matrix and diffuser. Because porous particles made by the AIBN system has very large surface areas, these are belong to the diffusers of the high diffusion ration and low total transmittance. Porous particles made by the SLS-SFS system are partial to hole particles, therefore, there are good effect on the aspect of the diffusion ration and total transmittance.
