Fluorine-containing poly-styrene-acrylate latex was prepared by means of pre-emulsifying semi-conti-nuous seed emulsion polymerization in three different emulsifier systems such as SDS/OP-10,NDS-86 and DNS-86/fluorine-containing emulsifier.Then,the effects of the emulsifiers on the morphology of the latex particles and the hydrophobic/oleophilic properties of the latex film were investigated.Moreover,the morphology of latex particles,the chemical composition,the elements on the film surface and the hydrophobic/oleophilic properties of the film were characterized respectively by means of TEM,FT-IR,XPS and water/oil contact angle test.The results show that the latex particles prepared in SDS/OP-10 emulsifier system display a snowman structure,while those prepared in DNS-86 or DNS-86/fluorine-containing emulsifier system display an uniform core-shell structure,which benefits the enrichment of fluorine on the film surface,and that the film of the latex prepared in DNS-86/fluorine-containing emulsifier system possesses the best hydrophobic and oleophobic properties due to the morphology of latex particles and the adopted emulsifiers.
