In order to meet the application of the flexible wings of the submersible, nanocomposite hydrogels(NC gels) was prepared. Preparation of polyglycidyl methacrylate (PGMA) microspheres and correspondingly NC gels were reported. PGMA microspheres were prepared and modified by N-Methyl-D-glucamine, followed by free radical polymerization of acrylamide in the presence of microspheres to construct nanocomposite hydrogel. FT-IR, XPS and DLS verified a successful introduction of hydroxyl groups during modification. The effects of the particle size and content of the microspheres on the swelling properties of the composite hydrogels were investigated. Hydrogen bonds between hydroxyl groups and polyacrylamide molecular chains play important roles to the swelling property of NC gels. The intermolecular interaction and the crosslinking density were enhanced by the hydrogen bonds, and resultantly, swelling ratio of NC gels decreases.

为了满足潜水器柔性翼的应用，制备了纳米复合水凝胶（NC gels）。报道了聚甲基丙烯酸缩水甘油酯（PGMA）微球的制备以及相应的NC凝胶。PGMA微球的制备和修饰是通过N-甲基-D-葡糖胺进行的，然后在微球存在下进行丙烯酰胺的自由基聚合，以构建纳米复合水凝胶。FT-IR，XPS和DLS验证了改性过程中羟基的成功引入。研究了微球的粒径和含量对复合水凝胶溶胀性能的影响。羟基和聚丙烯酰胺分子链之间的氢键对NC凝胶的溶胀性能起重要作用。氢键增强了分子间的相互作用和交联密度，结果降低了NC凝胶的溶胀率。
