摘要

高分子水凝胶是一类在医学、制药、软骨组织工程、人工肌肉、仿生制动器和吸附剂等领域具有广泛应用前景的高分子材料，但是由于高分子水凝胶的机械强度较低，很大程度上限制了其应用。近年来，高分子增强水凝胶受到许多国内外科学家的广泛关注。研究证明，增强后的高分子水凝胶具有抗溶胀性、较强的韧性、超高机械强度的特点，具有显著的应用价值。本文介绍了高分子水凝胶的概念、高分子水凝胶增强的机理，并详细归纳了高分子增强水凝胶的制备策略，主要包括浸泡在电解质溶液中制备水凝胶、纳米复合水凝胶、多网络水凝胶，总结了最新的研究进展。最后，基于目前高分子水凝胶存在的一些问题（如部分水凝胶生物相容性差、水凝胶在人体内无法降解、导电性差等），对未来高分子增强水凝胶发展以及可用于扩大天然材料应用领域、生物领域、环境修复领域做出了展望。

Abstract

Polymer hydrogel is a kind of polymer material which has wide application prospect in medicine

pharmacy

cartilage tissue engineering

artificial muscle

bionic brake and adsorbent. However

its applications are limited largely because of its low mechanical strength. In recent years

polymer reinforced hydrogels have attracted extensive attention from many scientists at home and abroad. It has been proven that the reinforced polymer hydrogels have the characteristics of anti-swelling

strong toughness and ultra-high mechanical strength

which possess significant application value. This paper introduces the concept of polymer hydrogel and its reinforcing mechanisms. And the strategies of preparation of polymer reinforced hydrogels are summarized in detail

including the preparation of hydrogels by immersion in electrolyte solutions

nanocomposites hydrogels and multinetwork hydrogels. Finally

based on some problems existing in current polymer hydrogel (such as some hydrogels have poor biocompatibility

cannot be degraded in human body and poor conductivity)

the future development of polymer reinforced hydrogels and their application in natural materials

biology and environmental remediation are prospected.
