利用FT-IR檢測聚胺基甲酸酯與DAD/clay反應過程中的鍵結變化；TEM來觀察奈米複合材料的表面結構形態。根據TGA測定結果，在加入DAD/clay後，其熱裂解溫度較?的聚胺基甲酸酯提升約9.37℃~36.21℃，利用UV-visible光譜儀分析檢測在可見光區呈現優異之光穿透性。在抗靜電物性方面，合成出的聚胺基甲酸酯/DAD/黏土光學薄膜表層塗佈有機抗靜電劑，Saftomer ST-2000H，後其表面電阻較純的聚胺基甲酸酯者有大幅降低之趨勢，其值從4.07×1013Ω/cm2降至8.29×107Ω/cm2，已達到一般抗靜電耐米複合材料的標準。 The main objective of this research is to study and develop the synthetic methods of highly heat resistant and anti-electrostatic WPU nano-composite materials. Firstly, DAD is used as a coupling agent to perform organic modification of clay and identify chemical linkage status with FT-IR. The nanocomposites were spin-coated with the spin coator at room temperature to form an optical thin film. The thermal properties, the surface resistance and light transparency were measured and discussed.
The crosslinking reactions between pure waterborne polyurethane and DAD/clay is investigated by FT-IR. The morphology structure of the nano-composites is observed with TEM. According to the results of TGA, the thermal decomposition temperatures (Td) of these nano-composites are 9.37℃~36.21℃ higher than that of pure waterborne polyurethane . The excellent transparencies of these thin films in visible light regions are detected by UV-visible spectrometer. On the aspect of anti-electrostatic property, the surface resistances of the WPU/DAD/clay thin films which was coated with organic anti-electrostatic reagent, Saftomer ST-2000H, is highly decreased from 4.07×1013Ω/cm2 to 8.29×107Ω/cm2. They have reached the standard scales of anti-electrostatic nanocomposites.
