Super-hydrophobicity of silica nanoparticles modified with vinyl groups

Super-hydrophobic silica nanoparticles with vinyl-modified silica nanoparticles (V-SiOx-NPs) weresuccessfully prepared. The resulting vinyl silica nanoparticles, were characterized by means of Fourier transformationinfrared spectroscopy and contact angles(CA). The results FT-IR and contact angles indicated that vinyl group had beensuccessfully grafted onto silica nanoparticles and contact angle showed hydrophobic silica nanoparticles from 30◦ wasraised to 130◦. This indicates that the chemical reaction is carried.The excellent superhydrophobic property enlargespotential applications of the superhydrophobic surfaces.
