Abstract:

Superhydrophobic-oleophobic coating with excellent antibacterial property was fabricated by chemical vapor deposition(CVD) on the surfaces of candle soot with silicon dioxide(SiO2) and trichloro(1H,1H,2H,2H-perfluorooctyl) silane(TMEDA). Morphological analysis by scanning electron microscope(SEM) showed that the candle soot possessed porous network nanostructure. The wetting property results by water contact angle characterization showed SiO2 deposited coating exhibiting superhydrophilic-lipophilic property which can be attributed to synergistic action of porous network nanostructure and SiO2. When further deposited by TMEDA on the surfaces of SiO2 deposited coating, not only the porous network nanostructure of coating was leaved behind, but also the superhydrophilic-lipophilic property of coating was transformed into superhydrophobic-oleophobic property. Such prepared superhydrophobic-oleophobic coating possesses higher antibacterial property by weakening the adsorption of bacteria on the solid surface. The synergistic action of superhydrophobic-oleophobic property and porous network structure leads to the excellent antifouling property of superhydrophobic-oleophobic coating. The superhydrophobic-oleophobic coating made up of candle soot may provide one new simple and effective approach for antibacteria in industrial unit and public environment.

Key words: Coating, Superhydrophobic, Oleophobic, Antibacterial property, Candle soot
