Abstract

A novel "three-step approach" of methanesulfonic acid/γ-aminopropyl triethoxy silane/GlycidylEthyl polyhedral oligomeric silsesquioxane (MSA/KH550/POSS) was proposed to functionalize the surface of high modulus poly (p-phenylene-2,6-benzobisoxazole) (HMPBO) fibers. Results indicated that GlycidylEthyl POSS was successfully grafted on the surface of HMPBO fibers and the surface roughness of HMPBO fibers was increased obviously. The single fiber pull-out strength of POSS-g-HMPBO/epoxy resin microcomposite was improved to 1.19 MPa, better than that of native HMPBO/epoxy resin microcomposite. POLYM. COMPOS., 35:611-616, 2014.
