摘要: 

分别将脂环族二酐单体1,2,3,4--环丁烷四酸二酐(CBDA, I)、1,2,4,5--环戊烷四酸二酐(CPDA, II) 和1,2,4,5--环己烷四酸二酐(CHDA, III)与芳香族含氟二胺1,4--双(4--胺基--2--三氟甲基苯氧基) 苯(6FAPB, a)和4,4´--双(4--胺基--2--三氟甲基苯氧基)联苯(6FBAB, b)反应制备两个系列的含氟半脂环族聚酰亚胺(PI), 研究了PI薄膜的热性能和光学性能.结果表明, 制备出的PI薄膜具有良好的热稳定性, 在氮气中起始热分解温度超过450℃、玻璃化转变温度超过250℃, 在可见光范围内(400--700 nm)具有优良的透明性,450 nm处的透过率超过88%. 两类PI薄膜在光通讯波段 (1.30 μm与1.55 μm)均没有显著的吸收.

Abstract

Three alicyclic dianhydrides, 1,2,3,4–cyclobutanetetracarboxylic dianhydride (CBDA,I),  1,2,4,5–cyclopentanetetracarboxylic dianhydride (CPDA, II), and 1,2,4,5–cyclohexane tetracarboxylic dianhydride (CHDA, III) were polymerized with two aromatic diamines, 1,4–bis (4–amino–2– trifluoromethylphenoxy) benzene (6FAPB, a) and 4,4´–bis(4–amino–2– trifluoromethyl phenoxy) biphenyl (6FBAB, b) respectively, via a two–step polycondensation procedure to afford two series of fluorinated semi–alicyclic polyimides (PIs). The PIs showed good thermal stability with the initial thermal decomposing temperatures higher than 450 °C in nitrogen and glass transition temperatures higher than 250 °C. The PI films exhibited good optical transparency in the visible light region (450–700 nm) with the transmittance higher than 88% at 450 nm. The PI films showed little absorption at the optocommunication wavelengths of 1.30 μm and 1.55 μm.
