Synthesis and modification of poly(benzobisoxazole)s

The synthesis technology for poly (benzobisoxazole) (PBO) was briefly introduced. The synthesis technologies for PBOs of linear alkene, condensed-ring aromatic hydrocarbon, diphenyl substituted group, and heterocycle were described in details. The research progress in the surface modification technologies of PBO fiber was reviewed, including plasma treatment, coupling agent treatment, corona treatment. The research of nano-modification technology for PBO was analyzed briefly, emphasizing the synthesis technologies of PBO/carbon nano-tubes (CNTs) composites and PBO/clay composites. It was pointed out that the research of poly(benzobisoxazole) be focused on the synthesis of high-relative molecular weight mass polymer, and the technologies of nano-modification, and the surface modification be introduced to improve the properties of PBO and expand its application.
