摘要
Abstract
By means of melt blending and extrusion blow molding method, low density polyethylene (LDPE)/zeolite molecular sieves(ZMS) composite films were prepared, and their mechanical properties, crystallinity and moisture permeability were tested. The crystallization performance and non-isothermal crystallization kinetics of the samples were analyzed with DSC. The results show that when the amount of ZMS increased, the tensile strength and elongation at break of LDPE/ZMS composite films assumed a little bit increase initially and then decreased. By blending ZMS with LDPE,the crystallization rate of LDPE increased. The ZMS had an effect on heterogeneous nucleation. With the amount of ZMS being increased,the capacity of moisture permeability of the composite films increased gradually. By using Jeziorny method amended with Ozawa equation, the crystallization of the composite films was characterized efficiently.关键词
