Abstract
A facile method for the preparation of silica/silicone nanofilament hybrid coatings with almost perfect superhydrophobicity(contact angle=179.88 and sliding angle=1.38) is presented.The coatings are obtained by dip-coating of silica nanoparticles,followed by chemical vapor deposition of silicone nanofilaments.
Predominant growth of silicone nanofilaments onto aggregated silica nanoparticles generates a two-tier structure.The effect of silica nanoparticle size on the growth of silicone nanofilaments, along with their anti-wetting properties and transparency are investigated in detail. Surface roughness and anti-wetting properties can be simply regulated by controlling the size of silica nanoparticles.
