摘要
利用伯胺分子层与二苯甲酮(BP)构成光引发体系在玻璃表面引发丙烯酸、丙烯酰胺、丙烯酸酯等的自由基接枝聚合。衰减全反射红外光谱、接触角与原子力显微镜的结果证明聚合物成功接枝于玻璃表面。以N,N-二甲基丙烯酰胺(DMAAm)为单体,研究了聚合条件的影响。当原料配比m(BP)∶m(DMAAm)∶m(acetone)=5∶100∶1000,反应时间为5min时,样品的接枝率和单位面积接枝量分别达到了0.330%和0.87mg/cm2,表面形貌发生了明显变化。结果表明接枝有PDMAAm的玻璃表面与丙烯酸树脂的粘接性能有显著提升。
UV-induced radical polymerization of acrylic acid, acrylate and acrylamide was carried out from the primary amine layers on the glass surface using benzophenone as the photo-initiator. Infrared spectroscopy, goniometry and atom force microscopy confirm that polymer chains are successfully grafted from the surface. The effect of reaction conditions on the polymerization of N, N-dimethylacrylamide was systematically evaluated. The maximum weight gain ratio and specific graft yield can reach 0.330% and 0.87 mg/cm2, respectively, for the polymerization with a feed ratio m （BP）： m （DMAAm）： m （acetone） = 5：100：1000 and a reaction time of 5 min. And the morphology varies significantly after the polymerization. Control experiments show that the glass-g-poly（N, N-dimethylacrylamide） （glass-g-PDMAAm） surface exhibits an enhanced adhesion property with acrylate resins.
