| Abstract | In this paper, we report on superhydrophobic fabric s (polyester, wool and cotton) produced by a wet-chemical coating technique. The coating so lutions were synthesized by the co-hydrolysis of two silane precursors, tetraethyl orthosilicate (TEOS) and an alkylsilane, in an alkaline condition. Without any purification, th e as-hydrolyzed solutions were directly used to treat fabrics, and the treated fabrics had w ter contact angles (CA) as high as 170o and sliding angles (SA) as low as 5o. Three alkylsi lanes have been used for the synthesis of the coating solutions, and all contain three hydrol ysable alkoxyl groups and one non-hydrolysable alkyl, but with different chain le ngths (C1, C8 and C16). It was found that the CA value increased with an increase in the alky l chain length, while the SA showed a reverse trend. When the functional group had a C16 alkyl, the treated fabric surfaces were highly superhydrophobic, with the CA not being affe cted much by the fabric type, while the SA values were slightly affected by the original we ttability of the fabric substrates. The superhydrophobic feature was attributed to a highly rough surface formed by the particulate coating. Aside from the superhydrophobicity, the in fluence of the coating on the fabric softness was also examined. |
