| 摘 要： | 为了提高聚乙烯薄膜的透气性能,采用挤出吹塑的方法制备了硅橡胶（聚二甲基硅氧烷,PDMS）含量为1%~5%的聚乙烯（PE）/硅橡胶共混薄膜,用扫描电镜研究了硅橡胶在聚乙烯中的分布,测试了共混膜的透气性能。结果表明,由于吹膜过程中的拉伸作用,硅橡胶颗粒呈细长型分布于聚乙烯基体中,硅橡胶的加入并不能明显改善聚乙烯的透气性能。...

| Abstract: | In order to enhance the gas permeability of polyethylene film,polyethylene/polydimethylsiloxane(PE/PDMS) blend film with 1%~5% PDMS was prepared by blow-molding method.Structure of the blend film was investigated by scanning electron microscopy,and gas permeability of the blend film was tested as well.As a result,PDMS particles dispersed in polythene matrix are stretched into strips during the process of blow-molding,and the gas permeability of the blend film cannot be significantly enhanced by adding PDMS compared with conventional polyethylene film.The gas permeability of PE/PDMS blend film was interpreted by gas-resistance model of composite polymer film,so it is suggested that the gas permeability of PE/PDMS blend film could be greatly increased only when PDMS particles penetrate into the PE film matrix. |
