摘要

摘要: 以3 , 3’- 4 , 4’- 二苯甲酮四甲酸二酐(BTDA) 、4 , 4’- 二胺基二苯醚(ODA) 和三氟乙酰丙酮银(AgTFA) 为主要原料, 采用原位一步自金属化法制备了银含量为9 %～15 %的聚酰亚胺( PI) / 银(Ag) 复合膜, 探讨了影响薄膜性能的各种因素, 得到了同时具有高导电(表面电阻～1Ω) 、高反射率(绝对反射率为65.3 %) 的PI/ Ag 薄膜。并通过透射电镜( TEM) 研究了薄膜热处理过程与亚微相态之间的关系, 定量探讨了反射率与固化时间之间的动力学方程。

Abstract: Surface silvered (Ag) polyimide films containing different silver mass f raction f rom 9 % to 15 % basedmainly on 3 , 3’- 4 ,4’- benzophenonetet racarboxylic acid dianhydride (BTDA) , 4 , 4’- oxydianiline (ODA) and t rifluoroacetylacetone (AgTFA) were fabricated by an in si tu single-stage self-metallization process , factors influencingthe film properties were investigated , meanwhile , highly conductive (Surface resistance is about 1Ω) and highly reflective (Absolute reflectivity is 65.3 %) surface silvered polyimide films were obtained. Additionally , the relationship s between the submicron morphology and properties of the films are observed and the dynamic equation betweenreflectivity and cure time is explored for the first time.
