摘要：

以9,9-双（3-氟-4-氨基苯基）芴和4,4（六氟异丙烯）二酞酸酐为单体合成含芴聚酰亚胺(FFDA-6FDA), 并采用Fourier变换红外光谱(FT-IR)、核磁共振氢谱(¹H NMR)对其结构进行表征. 实验结果表明: FFDA-6FDA的结构与预期结果相同, 单体间酰亚胺化反应完全; 室温下FFDA-6FDA在多种常规有机溶剂中溶解性良好； FFDA-6FDA具有较高的热稳定性能, 其玻璃化转变温度为370 ℃, 氮气中10%热失重温度为582 ℃, 800 ℃的热残留率大于61%； FFDA-6FDA薄膜具有较好的光学透明性, 截断波长为294 nm.

关键词: 聚酰亚胺, 光学透明性, 热稳定性, 可溶性

Abstract:

A polyimide containing fluorene group was prepared by 9,9-bis(3-fluoro-4-aminophenyl) fluorene and 4,4′(hexafluoroisopropylidene) diphthalic anhydride as a monomer. The structure of polyimide was characterized by Fourier transform infrared spectoscopy (FTIR) and nuclear magnetic resonance hydrogen spectrum (¹H NMR). Experimental results show that the structure of FFDA-6FDA is the same as the expected results, and the imidization reaction between monomers is conducted completely. FFDA-6FDA has good solubility in most common organic solvents at room temperature. FFDA6FDA has high thermal performance: its glass transition temperature is 370 ℃, the temperature at 10% weight loss is 582 ℃ and the weight maintenance rate in 800 ℃ is beyond 61% in nitrogen atmospheres. Furthermore, the thin film of FFDA6FDA has good optical transparency with 294 nm UV cutoff wavelength.

Key words: polyimide, optical transparency, thermal stability, solubility
