A facile method to prepare multifunctional PBO fibers: simultaneously enhanced interfacial properties and UV resistance

摘要: A new method combining surface coating with chemical grafting to prepare poly(p-phenylene benzobisoxazole) fiber–silica–graphene oxide (PBO–SiO2–GO) hybrid fiber was proposed. The composition, morphology, roughness (Ra), energy, interfacial shear strength (IFSS), single filament tensile (TS) and ultraviolet (UV) resistance of PBO fibers before after modification were investigated. Experimental results revealed that the covered by a silica coating, onto which GO successfully grafted through bonds. Ra energy PBO–SiO2–GO obviously increased in comparison an untreated one. IFSS its composites greatly improved due excellent wettability mechanical interlocking GO. Meanwhile, TS had no obvious decrease process. Moreover, introduction on led better UV than We believe this effective may provide novel strategy for developing multifunctional fibers.
