    • 本研究針對有功能性填料應用於調光節能薄膜與光擴散板之材料製程、光學特性及應用性加以探討。
    第一部分，功能性填料應用於調光節能薄膜: 實驗結果顯示，由於ITO-Al2O3粒子團聚性略高而造成光穿透率降低，致使最終霧度值較高。若探討雙層配置效應膜對於其近紅外波長遮蔽效果，以塗佈ITO-Al2O3塗料形成一阻氣之處理底層與Aminium salt塗膜為表層互相搭配結果顯示，近紅外光遮蔽效果是最佳的，其近紅外光穿透率為39%，可見光穿透率也可到82%，表面電阻值達到2.87×107(Ω/square)，此雙層配置膜將具有可見光穿透率佳、近紅外遮蔽效果佳的光學特性又兼具抗靜電特性，深具近紅外光遮蔽薄膜應用的潛力。
    第二部分，功能性填料應用於光擴散板: 實驗上，使用二段式聚合之方式製備(聚甲基丙烯酸甲酯)PMMA 預聚物，並獲得最適合之加工參數。預聚合物(Prepolymer)的黏度控制於3500~4000cP之範圍，以聚混摻方式，添加2.5 ~ 15不同重量百分比光學擴散劑，最後以鑄膜法製備成PMMA光學擴散板，實驗結果顯示，光擴散板的可視角(AOV)，霧度(Haze)會隨著光學擴散劑(ODA)的折射率提高而增加；而光學擴散劑平均粒徑愈小，光擴散板之體積含有率( volume fraction )會愈高，則產生光散射與折射之機率亦隨之昇高，因而促使可視角，霧度之有提高之趨勢，亦即可得較佳光擴散性能，當光學擴散劑添加量增加時，其遮蔽效果越佳，光擴散效率越好，使得光線更均勻分配。

    The objectives of this study are to investigate the function filler process, optical properties and application of intelligent window optic films and optical diffusion plate.
    Part A, function filler applied to intelligent window optic films: Results showed that, due to ITO-Al2O3 nanoparticles have higher agglomeration and lower light transmittance and leading to higher haze degree. To study on the near-infrared shielding effect of double-layered film toward, results showed that a resistance gas layer formed by ITO-Al2O3 coating collocating with Aminium salt film result the optimized condition of transmittance of near-infrared light which is 39%, the transmittance of visible light is 82%, and the surface electrical resistivity reached 2.87×107(Ω/square). This double-layered film possesses good transmittance of visible light and near-infrared shielding effect by the optical properties, and also the anti-static characteristics. Therefore it owns high potential for NIR-cut film application.
    Part B, function filler applied to optical diffusion plate: on the experiment, used the two-steps Polymerization of MMA monomer to get the optimum processing parameters of PMMA pre-polymer; then, added 2.5~15 wt% different concentration of optical diffusion particle polymer-blend into the PMMA prepolymer viscosity controlled during 3500-4000 cp of optimum condition, finally, manufactured PMMA optical diffusion plate by casting molding. Experiment show the following results︰ (1) the angle of View (AOV) and Haze of the diffusion plate goes up as the optical diffusion agent (ODA) refractive index rise, (2) As the particle size of ODA becomes smaller, and the volume fraction of the powder in the diffusion plate become higher, and the probability of causing light scattering get higher. So the trends are toward higher the angle of view (AOV) and Haze getting better diffusion performance.
