The hydrophilicity of poly(vinylidene fluoride) (PVDF) was first improved by in situ polymerization of polar monomer in PVDF solution. Methyl methacrylate was adopted as the reaction monomer, and the polymerization occurred in a solution of PVDF in N,N-dimethylformamide. PVDF/poly(methyl methacrylate) (PMMA) blend was obtained after in situ polymerization. The relative hydrophilicity of the in situ blend was characterized by contact angle measurement. At the same time, the hydrophilicity of the PVDF/PMMA blends prepared by solution blending was compared with that of the in situ blend. The contact angle measurements indicated that in situ polymerization has a stronger modifying effect on the hydrophilicity of PVDF than solution blending.
