Abstract
In this paper, bisphenol-a poly(aryl ether ketone)s containing methyl and trifluoromethyl were synthesized respectively, and transparent polymer films were obtained by the sol-gel method. The structures of two poly(aryl ether ketone)s were determined by 1H-NMR. DSC study showed that the Tg of the bisphenol-a poly(aryl ether ketone)s with main chain containing methyl (BPA-PAEKs) was 159oC, and that the Tg of poly(aryl ether ketone)s with main chain containing trifluoromethyl (6FBPA-PAEKs) was 166oC, and the 5% weight loss of both polymers was more than 460oC, showing good thermal stability. Through the study on the contact Angle, it was found that the water contact Angle of the BPA-PAEKs was 78o, and that the water contact Angle of the 6FBPA-PAEKs was 91o, the latter shows better hydrophobic performance.
