智能可控释放材料由于具有多种潜在的用途而引起广泛关注。其中,具有pH响应性的可控释放材料被认为是较易获得并对外界环境刺激响应较敏感的一类智能响应性材料。本文综述了具有不同结构的pH响应性可控释放材料的研究进展,包括pH响应性微胶囊、pH响应性聚合物微球、pH响应性水凝胶、pH响应性介孔材料的制备、可控释放作用及其应用。
Smart controlled release materials have attracted a great deal of attention due to their potential applications. Among them, pH-responsive controlled release materials are considered as a type of smart responsive material that is more accessible and sensitive to external environmental stimuli. This review summarizes the research progress of pH-responsive controlled-release materials with different structures, including pH-responsive microcapsules, pH-responsive polymer microspheres, pH-responsive hydrogels, pH-responsive mesoporous materials, Controlled release and its application.
