Yanwei Li, Jun Li, Yuanjun Song, Zhen Hu, Feng Zhao and Yudong Huang In situ polymerization and characterization of graphene oxide-co-poly(phenylene benzobisoxazole) copolymer fibers derived from composite inner salts Journal of Polymer Science Part A: Polymer Chemistry 51
A novel procedure through composite inner salts is presented based on the design and preparation of poly(phenylene benzobisoxazole) (PBO) copolymer fibers with well-dispersedgraphene oxide (GO). Three dimensional networks of PBO molecular chains and well dispersed GO particles are successfully constructed in GO-co-PBO copolymer fibers. The intensified interface strength and increased load transfer capacity between GO nanoparticles and PBO matrix result in GO-co-PBO copolymer fibers with significantly higher mechanical and thermal properties than PBO fiber.
