Abstract

A soluble photosensitive polyamide ester precursor (BAFPAE) was synthesized through copolymerization of 2,2-bis [4-(4-aminophenoxy)phenyl]hexafluoropropane (HFBAPP) with 4,4'-(4,4'-isopropylidenediphenoxy)bis(phthalic anhydride) (BPADA). Hydroxyethyl methacrylate (HEMA) was incorporated as a photosensitive functional group, and a transparent photosensitive polyimide film was obtained by thermal curing of the precursor film. The effects of reaction temperature and varying HEMA equivalents on the mechanical properties of the film were systematically investigated. The results indicated that the formation of polyacrylate-polyimide interpenetrating polymer networks (IPNs) was pivotal in preserving the mechanical integrity of the material. The optimized BAF-- exhibited a toughness of 12.69 MJ m, a Young's modulus of 2.86 GPa, an elongation at break of 21.16%, and a tensile strength of 92.68 MPa.

摘要

通过2,2-双[4-(4-氨基苯氧基)苯基]六氟丙烷(HFBAPP)与4,4'-(4,4'-异丙基二苯氧基)双(邻苯二甲酸酐)(BPADA)共聚合成了一种可溶性光敏聚酰胺酯前体(BAFPAE)。引入甲基丙烯酸羟乙酯(HEMA)作为光敏官能团，通过前体膜的热固化得到透明的光敏聚酰亚胺膜。系统研究了反应温度和不同HEMA当量对膜力学性能的影响。结果表明，聚丙烯酸酯-聚酰亚胺互穿聚合物网络(IPNs)的形成对于保持材料的机械完整性至关重要。优化后的BAF-表现出12.69 MJ/m的韧性、2.86 GPa的杨氏模量、21.16%的断裂伸长率和92.68 MPa的拉伸强度。
