摘要：The surface fluorinated polypropylene and PP (SFPP/PP) blend was obtained by direct fluorination of polypropylene particle with 3% F-2/N-2 gas and subsequent blending with polypropylene particle. The analyses indicated that the mechanical and thermodynamic properties of SFPP/PP blends such as tensile strength, impact strength, flexural strength, and cooling crystallization characteristics varied with the ratio of SFPP/PP. With the increase of SFPP in the blend, the tensile strength was decreased, while the impact strength and flexural strength might be improved. Meanwhile, fluorination resulted in the rise of melting point of PP. and in the DSC plot of SFPP/PP, annealing made the melting single peak split into double peak, which demonstrated that SFPP and PP were compatible but instable.
