本研究中利用含氟官能基團之單體合成聚醯亞胺(PI)前驅物聚醯胺酸(PAA),加入矽烷耦合劑,再將TEOS和APrTEOS進行溶膠-凝膠(sol-gel)反應形成水解液加入PAA中,將奈米級的SiO2導入聚醯氨酸形成PAA/Silica複合材料,再經由管狀高溫爐梯度升溫得到聚醯亞胺-二氧化矽複合材料,在此研究中探討不同耦合劑及水解液對聚醯亞胺-二氧化矽複合材料性質之影響。
添加SiO2進入PI使得熱性質有所提升,而加入耦合劑有效提高 SiO2在PI之分散性而不團聚,使得 複 合材料仍然保持透明。
In this study, we used two kind of -CF3 containing monomers,4,4-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) and 2,2-bis(trifluoromethyl)benzidine (TFMB) to synthesize the poly (amide acid) (PAA) solution, the precursor of polyimide (PI).Then, coupling agent was added into the above solution under stirring for 6 hours. Through sol-gel of (3-amino-propyl)triethoxysilane (APrTEOS) or tetraethoxysilane (TEOS), the PAA-silica solution was obtained. Finally, the mixture was casted on the glass substrate and then thermally imidized by stepwise heating to obtain the PI-silica composite. In this study, we investigated the properties of PI-silica composite with different coupling agent and sol-gel solutions.
Silica was added into the PI to improve its thermal property . The coupling agent can further improve the dispersion of silica in the PI composites to make it still highly transparent.
