摘要

A series of poly(γ-benzyl L-glutamate) (PBLG) and poly (γ-benzyl L-glutarnate)-block-poly(ethylene glycol) (PBLG-block-PEG) mixture films (mole ratio is 1:1) modified by polyurethane were prepared by casting the polymer blend solution in N,N-dimethylformamide. Surface morphologies of the polymer blend films were investigated by scanning electron microscopy. Mechanical and chemical properties of the polymer blend films were investigated by tensile tests and surface contact angle tests. It was displayed that the introduction of polyurethane could markedly affect the properties of the polymer blend films.
