采用分步悬浮聚合法制备了具有疏水性能的聚二乙烯基苯(polydivinyibenzene,PDVB)为第一网,具有亲水性能的聚丙烯酰乙二胺(polyacrylethylenediamine,PAEM)为第二网的疏水/亲水大孔聚二乙烯基苯/聚丙烯酰乙二胺(PDVB/PAEM)互穿聚合物物内网络(interpenetrating polymer networks,IPN),研究这类疏水/亲水IPN组成的树脂对吸附质的吸附热力学和吸附动力学;测定了该树脂对香兰素在不同温度下的吸附等温线,吸附等温线符合Freundlich 等温吸附方程,利用热力学函数关系计算出了吸附焓、自由能和熵变.实验表明,PDVB/PAEMIPN树脂中疏水性的 PDVB 网具有疏水作用吸附能力,亲水性的PAEM网具有氧键作用吸附能...

Hydrophobic-hydrophilic macroporous polydivinylbenzene/ polyacrylethylenediamine interpenetrating polymer networks (PDVB/PAEM IPN) were prepared by the sequential suspension polymerization method. These were composed of two networks, of which one was hydrophobic (PDVB) and the other was hydrophilic (PAEM). The objective of this work was to study the adsorption thermodynamics and adsorption kinetics of this hydrophobic-hydrophilic IPN. The focus was on adsorption isotherms of vanillin at different temperatures, and these fit well into the Freund...
