1 PROGRESS IN CHEMISTRY Vol. 22 No. 6 Jun * O O A X Structures and Surface Wettability of Fluorinated Meth Acrylate Polymers Yang Hao Pi Pihui Wen Xiufang Zheng Dafeng Cheng Jiang Yang Zhuoru School of Chemistry and Chemical Engineering South China University of Technology Guangzhou China Abstract Fluorinated meth acrylate polymers are a class of novel low surface energy materials in which the fluorinated chains confer them hydrophobic and oleophobic properties and the non-fluorinated chains render them fine solubility and compatibility. The surface wettability can be changed by designing and controlling the structures of fluorinated meth acrylate polymers. In this article we review the influence factors of surface wettability for fluorinated meth acrylate homopolymers random block graft core-shell copolymers and crosslinked network copolymers etc. The relationships between the structures and surface wettability including wetting stability of the polymers are discussed by means of analyzing the crystallinity surface element content surface energy and contact angle of the polymers and the related models are also given which providing theoretical basis and guidance for design and synthesis of stable surface wettability of fluorinated meth acrylate polymers.
