Abstract

A series of poly(gamma-benzyl L-glutamate)-block-poly(ethylene glycol)/poly(tetramethylene glycol) (PBLG-block-PEG/PTMG) blend films were prepared by casting the polymer blend solution in dichloroethane. Surface morphologies of the PBLG-block-PEG/PTMG blend films were investigated by scanning electron microscopy and atomic force microscopy. Mechanical and chemical properties of the polymer blend films were studied by tensile tests and surface contact angle tests. It was shown that the introduction of poly(tetramethylene glycol) could greatly affect the properties of the polypeptide block copolymer films.
