【摘要】：作为一种基体中含有大量水的交联聚合物材料,聚合物水凝胶已经被广泛应用于食品、化妆品和生物医药等很多领域。然而,传统聚合物水凝胶机械性能不足,这限制了其在高技术领域的进一步应用。近十几年来,一系列具有规整或特殊网络结构的高强度聚合物水凝胶的出现在很大程度上改善了这一状况,在这些水凝胶中,复合水凝胶、双网络水凝胶、类四面体型聚乙二醇大分子单体水凝胶(Tetra-PEG水凝胶)和拓扑凝胶是典型代表。然而,为了使水凝胶在诸如人造组织、可穿戴设备和3D打印等高技术领域实现更多应用,赋予其功能性与提高其机械性能同等重要,因此,在对高强度水凝胶的结构和基本性能深入研究的基础上,对其进行功能化便引起了广泛关注。本文综述了近年来对高强度聚合物水凝胶进行功能化的研究进展,重点从上面提到的四类高强度水凝胶展开综述和讨论,并对该领域所面临的挑战和未来的研究方向进行了简要讨论和展望。
[Abstract]:As a cross-linked polymer material with a large amount of water in the matrix, polymer hydrogel has been widely used in many fields, such as food, cosmetics, biomedicine and so on. However, the traditional polymer hydrogel has insufficient mechanical properties. This limits its further application in the field of high technology. In recent decades, the emergence of a series of high strength polymer hydrogels with regular or special network structures has greatly improved the situation, in these hydrogels, Composite hydrogels, double network hydrogels, tetrahedral polyethylene glycol macromonomer hydrogels (Tetra-PEG hydrogels) and topological gels are typical. Wearable devices and 3D printing and other high-tech areas to achieve more applications, to give its functionality as important as to improve its mechanical properties, therefore, based on the structure and basic properties of high-strength hydrogels, In this paper, the research progress on functionalization of high strength polymer hydrogels is reviewed, with emphasis on the four kinds of high strength hydrogels mentioned above. The challenges and future research directions in this field are briefly discussed and prospected.
