Aqueous e-ATRP Synthesis of Temperature-Responsive Microgels:New Experimental Design and Practice of Polymer Microgel

This paper illustrates a laboratory training experiment covering polymer chemistry,electrosynthesis and instrumental analysis.In this experiment,the temperature-responsive microgel is synthesized following e-ATRP via electrochemically active polymerization on a commercialized electrochemical reaction device,and then temperature-responsive property of the microgels is characterized by using UV-Vis spectrophotometer and dynamic light-scattering.This experiment is based on the research of cutting-edge topics,allowing expanding to the synthesis of other polymers or using a variety of electrochemical technology,which is helpful to train the students’awareness of interdisciplinary integration thinking and environmental awareness,and to train the students’innovation ability.
