Abstract
The increasing environmental burden in human society calls for the development of more environmentally benign technologies and sustainable applications. Wastewater contaminated by oil or organic solvents has become a serious environmental issue nowadays. Herein, a well-defined thermosensitive block copolymer was designed and used for controllable water/oil separation. The functional material poly(2,2,3,4,4,4-hexafluorobutyl methacrylate)-block-poly(N-isopropylacrylamide) was synthesized through a new environmentally benign “living” radical polymerization technique [i.e., photoinitiated atom-transfer radical polymerization (photoATRP)]. The synthesized functional copolymer was considered as a modifier for fabricating a smart surface with thermal-responsive wettability. The switchable mechanism, surface composition, and morphology of the as-fabricated surface were investigated by water contact-angle measurement, X-ray photoelectron spectroscopy, and atomic force microscopy. Results showed that the as-fabric...
