摘要
选取聚酰亚胺(PI)作为有机高聚物基体,通过正硅酸乙酯及异丙醇铝在聚酰胺酸的 N,N-二甲基乙酰胺溶液中进行溶胶-凝胶反应,制备SiO2和Al2O3质量分数不同的聚酰亚胺杂 化薄膜.并且分别利用原子力显微镜、傅里叶变换红外光谱、热重分析和介电谱对两种(原始的和 掺杂的)薄膜的表面形貌、结构、热性能和介电性能进行了表征和测试.
Using polyimide as the matrix resin and by the Sol-Gel process of traethoxysilane (TEOS) and heteropropyl-aluminium in PAA solution of DMAc, polyimide composite film with a varied amount of SiO2 and Al2O3 was prepared. Two (original and dopped) PI films' surface morphology and structure were characterized and measured by IR, AFM,TGA and dielectric spectroscope.
