A novel type of polymer nanocomposite (NC) hydrogel with extraordinary mechanical properties at low inorganic content is prepared and investigated. The NC hydrogels consist of isethionate-loaded layered double hydroxide/polyacrylamide (LDH-Ise/PAM) - with LDH-Ise being used because of its swelling properties - and no conventional organic crosslinker. The NC hydrogels exhibit an unusual hierarchical porous structure at the micro- and nanometer scales, and their elongation at break can exceed 4000%.
制备并研究了一种新型聚合物纳米复合材料（NC）水凝胶，其在低无机含量下具有非凡的机械性能。NC 水凝胶由载有伊士酸盐的层状双氢氧化物/聚丙烯酰胺（LDH-Ise/PAM）组成 - 之所以使用 LDH-Ise 是因为其具有溶胀性能 - 且不使用常规的有机交联剂。NC 水凝胶在微观和纳米尺度上呈现出异常的分级多孔结构，其断裂伸长率可超过 4000%。
