Abstract
Poly(dimethylaminoethyl methacrylate)-è/ocÂ:-poly(methyl methacrylate) (PDMAEMA-è-PMMA) copolymer (BCP) was synthesized as a amphiphilic compatibilizer via reversible-addition fragmentation chain transfer polymerization to improve the interfacial adhesion and compatibility between epoxy sizing of carbon fiber (CF) surface and polypropylene (PP) matrix. The pristine CF (p-CF)/PP and compatibilizer-treated CF (BCP-CF)/PP composites were fabricated using melt mixing and their tensile properties were analyzed. It was confirmed that the CF surface was func-tionalized with BCP by reaction of tertiary amine in BCP with epoxide group on CF surface through XPS, TGA and FE-SEM. The tensile strength and modulus of BCP-CF/PP composites were improved by 37.8% and 18.7%, compared to p-CF/PP composites, which could be attributed to the higher interfacial adhesion between CF and PP and thus improved load transfer capability. The enhanced interface adhesion and compatibility of BCP-CF and PP was also examined by morphology observation.
