摘要:
以对羟基苯甲酸(p -HB)为模板分子,从4-乙烯基吡啶(4-VP)、丙烯酰胺(AM)和甲基丙烯酸(MAA)3种具有代表性的单体中,选择最适宜制备p-HB分子印迹聚合物的功能单体。首先采用分子力学方法计算了p-HB与功能单体4-VP、AM和MAA的结合能,其强度顺序为:4-VP>
Abstract:
Molecularly imprinted polymers(MIPs)using p-hydroxybenzoic acid(p-HB)as template,4-vinylpyridine(4-VP),acrylamide(AM)and α-methylacrylic acid(MAA)as functional monomers were prepared separately. First,the binding energy of p-HB with the above monomers is calculated by using the molecular mechanics method. The order of binding energy of p-HB with different monomers is 4-VP>AM>MAA. Second,the interaction strength between p-HB and different monomers is studied by UV analysis, which is in the same order(4-VP>AM>MAA).Third, the static adsorption experiments of the MIPs using 4-VP,AM or MAA as functional monomer show that the binding capacity order of these MIPs is also 4-VP>AM>MAA,the same with those from molecular mechanics calculation and UV analysis. The results demonstrate that 4-VP is the best among the three monomers对羟基苯甲酸, 分子印迹聚合物, 功能单体, 分子力学计算, 吸附
