丙烯酰胺(AAM)接枝于嵌段聚醚氨酯(SPEU)膜上的聚合反应已有研究。Halpern等报道将聚氨酯膜先用紫外光预辐射再用铈盐引发AAM接枝,可以增加接枝密度;Kronick等报道用活化蒸汽法将AAM在膜表面上形成接枝层后,再在二苯酮光敏剂存在下,进行光引发接枝,可以增加接枝层的厚度。不加光敏剂用光引发AAM接枝于SPEU膜上,尚 Polymerization of acrylamide (AAM) onto block polyether urethane (SPEU) membranes has been studied. Halpern et al reported that the polyurethane film pre-irradiated with UV light and then initiated with AMA grafted cerium salt, can increase the graft density; Kronick et al reported activation of the AAM on the membrane surface to form a graft layer, and then in the benzene In the presence of a ketone photosensitizer, photoinitiated grafting can increase the thickness of the grafted layer. AAM grafted onto SPEU membrane without photosensitizer
