【Abstract】 The progress on the synthetic technology, properties, characteristic methods and application of Temperature- Sensitive microgel of poly (N-isopropylacrylamide) has been briefly reviewed. Firstly, the principle of the microgel formation and stabilization has been appraised. Secondly, the commonly used synthetic method of the microgel has been summarized, that is, the microgel was conveniently prepared by Surfactant-Free Emulsion Polymerization (SFEP) and Emulsion Polymerization (EP), in which the effect of different synthesis conditions on preparing the microgel was discussed as well. Later, the influence of different environment factors on the properties of the microgel and the microgel application in the fields of biotechnology, chemistry, medical science etc. has been commented.更多还原
