Surface hydrophobicity of an organosilicon film modified by a silver seed layer with the nanoparticle structures

In this work, a silver seed layer was deposited onto the silicon substrate prior to the deposition of the organosilicon film with the hydrophobic surface. Nanoparticle structures of the seed layer were formed after a post-annealing treatment. The surface morphology of the organosilicon film was well conformal to the silver seed layer with the nanoparticle structures. The resulting surface hydrophobicity evaluated from the water contact angle of the organosilicon film was markedly increased from 100 degrees to 122 degrees.
