摘要
具有核 壳结构的聚合物微容器不仅可以保护核内包封的物质,而且通过其壳层聚合物材料对环境酸碱度、离子强度、温度等条件的变化相应发生的分子链的可逆收缩与伸展,实现对核内物质的可控吸附和释放,在医学和生物学领域有着许多潜在的用途和优势。本文综述了近年来核 壳结构聚合物微容器的制备方法、智能化控制释放机制及其潜在应用研究进展。
Core-shell polymer microcontainers can protect the substances with in the core, and realize the controlled release by reversible shrinkage and extension of the shell’s molecules according to the change of acidity, alkalinity, ionic strength and temperature of theenvironment. Therefore the core-shell polymer microcontainers have many potential applications and advantages in medicine and biology fields. In this paper, the advance in the preparation process, intelligent controlled release mechanism and potential application of polymeric microcontainers is reviewed.
