摘　　要：综述了水凝胶研究的一些新进展。简要介绍了水凝胶中水的存在状态和水合氢键模型,分析了电解质影响水凝胶中水的分子状态和凝胶溶胀收缩的现象,并利用水合氢键模型加以解释,指出有待解决的相关问题。The research and development of hydrophilic polymers were reviewed in this paper. The structure of water molecules sorbed in different hydrophilic polymers and hydrogen-bonding hydration model in polymer were also discussed. The ion-specific swelling of polymer gels in various aqueous salt solutions was described. These ion-specific swelling behaviors were interpreted in terms of ion effects on the hydrogen-bonding hydration model and unsolved problems in this area were mentioned.
