摘要：
Poly(propylene carbonate) (PPC) is coated with cellophane (PT) via the intermolecular hydrogen bonds of chitosan (CS) with the both polymers, and their multilayer films are prepared in different weight ratios. The trace presence of chitosan on the surface of PT promotes the combination with PPC layers. After coating, the Young's modulus and tensile strength of PPC are greatly improved, the storage modulus still keep a high value between similar to 0-70 degrees C. The oxygen barrier of PPC is increased at least 580 times, and the multilayer films still keep good water vapor barrier in some degree.
