敏感性二氧化硅/高分子微凝胶复合材料既具有二氧化硅良好的化学稳定性、低毒性和易于功能性,又具有敏感性高分子微凝胶对外界环境(如温度、pH等)的刺激响应特性,因而广泛应用于药物控释、吸附分离、载体和微反应器等重要领域。本文根据二氧化硅和敏感性高分子复合结构的不同,对二氧化硅/高分子核-壳型复合微凝胶、高分子/二氧化硅核-壳型复合微凝胶及杂化网络结构二氧化硅-高分子复合微凝胶等三类复合材料的制备研究进展进行较为详尽地阐述和分析。
Sensitive silica / polymer microgel composites have good chemical stability of silica, low toxicity and easy functionality, but also has the sensitivity of polymer microgels to the external environment (such as temperature, pH, etc.) The stimulus response characteristics, which are widely used in drug controlled release, adsorption separation, carrier and microreactor and other important areas. In this paper, silica / macromolecular core-shell composite microgel, polymer / silica core-shell composite microgel and hybrid network structure Silica - polymer composite microgels and other three types of composite materials preparation of research progress in more elaborate and analysis.
