异丙酚分子印迹复合膜的制备

Preparation of molecularly imprinted composite membranes with propofol as template

目的:制备异丙酚分子印迹复合膜。方法:在紫外光照和引发剂的作用下,模板分子异丙酚、功能单体甲基丙烯酸(MAA)和交联剂乙二醇二甲基丙烯酸酯(EDMA)在聚偏氟乙烯(PVDF)微孔滤膜表面聚合形成分子印迹复合膜,考察模板分子和功能单体的结合特性,用扫描电镜表征膜的表面形态。结果:复合膜形态良好,异丙酚和甲基丙烯酸以氢键的方式缔合。结论:用紫外光照射法可以制得异丙酚分子印迹复合膜。

Objective： To prepare the molecularly imprinted composite membranes with propofol as template. Methods： With the ultraviolet light and initiator, template molecular propofol, functional monomer methacrylate and crosslinking agent ethylenegly-coldimethacrylate （EDMA） formed molecularly imprinted composite membrane through polymerization on the surface of polyvinyli-dene fluoride （PVDF） microporous membrane. Inspection of the combination of template molecule and functional monomer, characterization of the membrane surface morphology with scanning electron microscopy. Results： The morphology of composite membranes was well. Propofol bonded to methylacrylic acid with hydrogen bond. Conclusion： The method of ultraviolet light-struck is feasible for preparation of molecularly imprinted composite membranes with propofol as template.
