在氮气保护下,利用预辐照接枝技术在高密度聚乙烯(HDPE)膜上接枝苯乙烯三甲基氯化铵(VBTAC)单体,以甲基丙烯酸二甲氨基乙酯(DMAEMA)单体作为接枝辅助单体来提高VBTAC的接枝率,制备出阴离子交换膜,解决了在HDPE上难以直接接枝聚合VBTAC的问题。本文研究了接枝条件及接枝液的组分对接枝的影响,并用X射线显微分析方法研究了VBTAC的接枝进程和接枝分布。 Under the protection of nitrogen, the monomer of styrene trimethylammonium chloride (VBTAC) was grafted onto the high density polyethylene (HDPE) film by using the pre-irradiation grafting technique. With DMAEMA, Monomer as grafting auxiliary monomer to improve the grafting rate of VBTAC to prepare an anion exchange membrane and solve the problem of difficult direct graft polymerization of VBTAC on HDPE. In this paper, the grafting conditions and grafting liquid components on grafting were studied. The grafting process and grafting distribution of VBTAC were studied by X-ray microscopy.
