中文摘要：

综述了无机粘土（包括蒙脱石、海泡石和高岭土）、天然可再生基质（包括蛋白类、海藻酸类、甲壳素／壳聚糖类及腐植酸类）与有机高吸水树脂的复合改性研究进展，介绍了天然原材料的加入对复合吸水树脂的耐盐吸盐水性、吸水倍率、凝胶强度、降解性等性能的影响，最后提出了复合吸水树脂研究有待解决的问题。

英文摘要：

The research progress of compound modification between organic superabsorbent polymer and inorganic clay （including montmorillonite, sepiolite and kaolinite） and renewable natural polymer （including protein, alginate, chitin/chitosan and humic acid） is summarized. And the influence of adding natural materials into composite su-perabsorbent polymer is reviewed in terms of improvement of salt resistance, absorbing rate, hydrogel intensity, biodegradability, and so on. Finally, the problems to be solved in the future of composite superabsorbent polymer research are put forward.
