摘要
传统化学交联的聚丙烯酰胺(PAM)水凝胶由于力学性能较弱,其应用范围受到很大限制。与之相比,采用纳米复合技术制备的PAM纳米复合(NC)水凝胶,不仅大幅提高了力学性能,而且在溶胀率等方面也有明显的提高。本文结合该领域近年来的研究进展,将PAM NC水凝胶分为纯物理交联和化学物理交联相结合两类,重点讨论了NC水凝胶在力学性能方面的研究结果,对溶胀率等其它方面的性能也进行了综合论述。
The application of conventional chemically crosslinking polyacrylamide(PAM)hydrogels is seriously limited due to their poor mechanical properties.Novel PAM nanocomposite(NC)hydrogels exhibit greatly enhanced mechanical performances as well as the swelling ratios.In this review,two different NC hydrogels series,including via physical crosslinking and chemical crosslinking,were classified.The recent developments of the mechanical properties of these two types of PAM NC hydrogels were reviewed in details.In addition,other properties such as swelling ratios were discussed as well.
