摘要
本文综述了近年来有机-无机纳米复合水凝胶领域的研究进展。针对无机成分的不同种类及复合形式,本文将目前已见报道的有机-无机纳米复合水凝胶划分为三类,分别为层状硅酸盐纳米插层复合水凝胶、黏土交联纳米复合水凝胶和二氧化硅纳米杂化复合水凝胶。阐述了三类纳米复合水凝胶的发展趋势,特别就它们的合成方法进行了详细归纳与总结。在此基础上,介绍了纳米无机成分对复合水凝胶的性能增强机理,并就三者之间的增强差异进行了说明。
This review addresses the recent developments on the field of organic-inorganic nanocomposite hydrogels. Organic-inorganic nanoeomposite hydrogels are classified into three types based on different kinds of inorganic components, as well as their different complex forms with organic components： intercalated layered-silicate nanocomposite hydrogels, clay-crosslinked nanocomposite hydrogels and hybrid silica-based nanocomposite hydrogels. The developments on three types of nanoeomposite hydrogels are reviewed comprehensively. Especially their preparation methods are introduced in detail. It is followed by an overview of proposed strengthen mechanisms of inorganic components for the nanoeomposite hydrogels. The difference in the strengthen mechanism among three nanocomposite hydrogels are explained in more detail.
