Micro‐nanostructured silicone‐carbon composite coatings with superhydrophobicity and photoluminescence prepared by oxidative chemical vapor deposition

Abstract

Transparent, superhydrophobic, and colored silicone-carbon composite coatings were prepared by oxidative chemical vapor deposition (oCVD) of bulk silicone at ambient pressure. The colors, wettability, morphologies, and transparency of the coatings can be easily varied via changing both the concentration of gaseous oxygen and the deposition temperature. Typically, the black, brown, and yellow silicone-carbon composite coatings with different superhydrophobicity and transparency were achieved under oxygen-deficient atmospheres. Furthermore, the colored samples showed photoluminescence when they were excited by ultraviolet (UV) light, which is due to the fluorescence of carbons embedded inside the as-prepared coatings. In addition, more regular papillae and nanofibers with excellent superhydrophobicity were obtained at higher deposition temperatures. Our method was believed to develop a new strategy for fabricating multifunctional silicone-carbon composite coatings. V C 2014 Wiley Periodicals, Inc. J. Appl. Polym.Sci. 2014, 131, 40400.

Stable superhydrophobic surface based on silicone combustion product

“…Silicone elastomers based on polydimethylsiloxane (PDMS) are widely applied in the elds of high-voltage outdoor insulation, encapsulation and seal rings. Recently, they have been used to fabricate superhydrophobic surfaces [24][25][26] due to PDMS's multiple properties, such as low toxicity, long-term stability and a wide range of operating temperatures. PDMS (Sylard 184) was successfully used to prepare a transparent superhydrophobic coating mixed with silica nanoparticles.…”
