Synthesis and Characterization of Polyimide Containing Fluorene Group
摘要
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.关键词
