【摘要】 传统水凝胶存在机械性能差、响应速度慢等缺点,限制了它作为新材料的应用前景。纳米材料具有独特的微观尺度结构和性质,在电子学、光学、机械学、生物学等领域展现出巨大的潜力。将无机纳米材料添加入水凝胶中不但有可能提高水凝胶的机械强度,同时还能赋予凝胶特殊的新性能,如电响应性能、紫外吸收性能、磁敏感性能等。因而纳米复合水凝胶成为近期的研究热点。本文综述了纳米复合水凝胶的增强理论、典型制备方法及其功能化研究进展。更多还原

【Abstract】 The applications of the traditional hydrogels have been limited by their poor mechanical properties and low response rate.Introduction of inorganic nanoparticles,which have unique micro-scale structures and properties,and exhibit tremendous potential in the fields of electronics,optics,mechanics and biology,can not only enhance the mechanical strength of the hydrogels,but also endow them with new characters that sigle-phase materials do not have,such as electrical response,ultraviolet absobability,magnetic sensitivity etc.Therefore,hydrogels with nanoparticles have been interested by many researchers in recent years.In this paper,the reinforcement theories,typical preparation methods and progrecesses in functionalization of composite hydrogels were discussed.更多还原
