Abstract Polyacrylic acid/polyethersulfone (PAA/PES) capsules were adopted as templates to synthesize PAA/PES core–shell spheres, and the PES shell of spheres could be removed automatically by the swelling nature of the cross-linked PAA hydrogel core. By using the method, PAA hydrogel spheres were prepared with an ultrahigh ion exchange capacity of 12 meq g−1, and the spheres showed a high adsorption capacity for methylene blue. The PAA-polyacrylamide hydrogel spheres with dual adsorption ability and good mechanical property were also prepared. It was revealed that these two hydrogel spheres can be effectively utilized in the removal of environmental toxins.

一种具有超高离子交换能力和强吸附环境毒素的聚（丙烯酸）水凝胶球的模板孵化方法

摘要 以聚丙烯酸/聚醚砜（PAA/PES）胶囊为模板合成了PAA/PES核壳球体，通过交联PAA水凝胶核的溶胀特性，球体的PES壳可以自动去除。利用该方法制备了具有12 meq g-1的超高离子交换容量的PAA水凝胶球，该球对亚甲蓝显示出较高的吸附能力。还制备了具有双重吸附能力和良好机械性能的PAA-聚丙烯酰胺水凝胶球。结果表明，这两种水凝胶球可以有效地用于去除环境毒素。
