摘要: In this study, novel aminated poly(phthalazinone ether ketone) (PPEK-NH2) with amino groups on main chains was synthesized by typical condensation polymerization of 4-(4-Hydroxylphenyl)(2H)-phthalazin-1-one (DHPZ), 4,4'-difluoro benzophenone (DFK), and the third active monomer, 1,5-diamino-4,8-dihydroxyanthraquinon (DDT). As a type of compatibilizer, PPEK-NH2 was utilized to modify the interface properties of carbon fibers (CF) reinforced copoly(phthalazinone ether sulfone)s (PPBES) composites. The composites were prepared by solution impregnation and compression molding, where PPEK-NH2 was distinguished by different mole ratios of DHPZ/DFK/DDT. And the effects of amino structural unit quantity in PPEK-NH2 chains on compatibility was investigated. Of all the compatibilizers, PPEK-NH2 (4) exhibits the best compatible effect. The interlaminar shear strength and flexural strength of CF/PPBES increased significantly by 15.8% and 26.2%, respectively. According to DMA test, the storage modulus and service temperature increase by 12 GPa and 7 degrees C, respectively. Beside, CF/PPBES/PPEK-NH2 (4) exhibits excellent mechanical behaviours with at 240 degrees C and 250 degrees C. Moreover, this composite also demonstrates excellence in hydrothermal aging tests. This method contains simple process, large-scale application potential, which offers new insights for fabricating high-performance advanced thermoplastic composites.
