本計畫係以開發近紅外光遮蔽之高分子複合材料應用於透明隔熱塗料，透過混摻紅外光遮蔽無機奈米顆粒(如ITO、LaB6、和Cs0.33WO3)於高分子薄膜中可提高近紅外光遮蔽的效率和波長範圍，太陽光所產生的近紅外波長範圍(800~2500 nm)的輻射(熱射線)可有效率地被吸收或反射，並維持可見光區域之高穿透度。因此，具有近紅外光遮蔽及高可見光穿透度的高分子複合材料中以減少使用空調能源之消耗，從而減低二氧化碳的排放，達到綠能與節能之目的。另外，近紅外光遮蔽無機奈米顆粒可透過表面改質給予官能化，來改善近紅外光遮蔽無機奈米顆粒和高分子樹脂之間的分散性、流動性(降低黏度)、相容性、減少霧度及維持機械性質。

Novel near infrared (NIR) shielding polymer composites containing near IR shielding inorganic nanoparticles (such as ITO, LaB6, and Cs0.33WO3) are developed in this project to the applications of transparent heat-insulated coatings. To enhance the absorption efficiency and to cover broader wavelength ranges of NIR, the radian wavelength of NIR (800~2500 nm) (heat rays) from sun can be effectively absorbed or reflected by doping near IR shielding inorganic nanoparticles in polymer films to maintain the high transmittance of visible light. Hence, the goal of energy saving and green energy can be achieved by the near IR shielding and high transmittance of visible light in polymer composites to reduce the consumption of air conditioning energy and CO2 release. In addition, the NIR shielding nanoparticles can be surface-modified with functional groups to improve the compatibility, reduced-haze, mechanical properties, dispersion and liquidity (reduce the viscosity) between polymer and NIR shielding nanoparticles.
