摘　　要：随着柔性光电技术的快速发展,制备出具有优异综合性能的聚酰亚胺成为当前的研究热点。本工作采用自制的对亚苯基双苯偏三酸酯二酐和三种含不同取代基团的4,4′-二氨基二苯基甲烷进行反应,制备了三种聚酯酰亚胺树脂,表征了树脂的热性能、溶解性能、力学性能、光学性能。研究发现:对亚苯基双苯偏三酸酯二酐和2,2′-二(三氟甲基)-4,4′-二氨基二苯基甲烷制备的聚酯酰亚胺薄膜,具有较高的玻璃化转变温度和良好的可见光透过率,有望应用于柔性光电领域。With the rapid development of flexible photoelectric technology,the preparation of polyimides with excellent comprehensive properties has become a research hotspot.A series of poly(ester imide)s were prepared by polycondensation of bis(trimellitic acid anhydride)phenyl ester(TAHQ)and three 4,4′-diaminodiphenylmethaners with different substituent groups,and their thermal properties,solubility,mechanical properties and optical properties were studied.The results showed that the polyimide films prepared by TAHQ and 2,2′-bis(trifluoromethyl)l-4,4′-diaminodiphenylmethaner had high glass transition temperature and good visible transmittance,which were expected to be applied in the field of flexible optoelectronics.
