英文摘要： In the near future, both development of novel and efficient smart membrane materials and enhancement of smart membrane processes will be the main focus of research in the field of smart membranes. In this proposal, the idea that the amphiphilc diblock smart copolymer fabricated by living free-radical polymerization are blended with membrane materials and cast into microporous smart gating membranes with smart hydrophilic block "gates" exposed on the membrane surface and pores via immersion precipitation method has been developed innovatively. It plans to precisely control the chemical structure and composition, shape, molecular weight and distribution, polymerization degree of the amphiphilic diblock smart copolymer at first, to systematically study the controllable law of the parameters (such as chemical structure) of smart copolymer and the precise physical/chemical microstructure of smart gating membrane, as well as the controllable law of the precise physical/chemical microstructure and performance of smart gating membrane, to verify the key issues such as the mechanism of kinetic phase separation during the membrane-forming, to achieve precise and reliable regulation of performances such as stimuli-responsiveness of smart gating membranes, to gain the microporous smart gating membranes with good stimuli-r
