BDAPPP型聚酰亚胺薄膜的制备及性能研究

Preparation and performance study of BDAPPP type polyimide film

以双酚A、2,4-二硝基氯苯、马来酸酐(MA)、4,4′-二氨基二苯醚(ODA)、3,3′,4,4′-四甲酸二苯醚二酐(ODPA)为主要原料,经三步法合成得到BDAPPP型聚酰亚胺(ODPA/44ODA/MA/BDAPPP-PI)薄膜。采用红外光谱分析、热失重分析、力学性能分析和介电分析对该薄膜进行表征。结果表明:BDAPPP型聚酰亚胺薄膜具有良好的耐热性能、优良的力学性能和绝缘性能。

With bisphenol A,2,4-nitrochlorobenzene,maleic anhydride（MA）,4,4′-diamino diphenyl ether（ODA）,3,3′,4,4′-tetracarboxylic acid diphenyl ether dianhydride（ODPA）as the raw material,BDAPPP type polyimide was synthesized through three steps and the ODPA/44ODA/MA/BDAPPP-PI thin film was prepared.By means of infrared spectrum analysis,thermo-gravimetric analysis,mechanical property analysis and dielectric characterization of thin film,the results showed that BDAPPP type polyimide film had good heat resistance,excellent mechanical properties and insulation performance.
