The control of surface wettability through a combination of surface roughness, chemical composition, and structural modification has attracted significant attention for a variety of applications. In this thesis, amphiphilic organic-inorganic hybrid materials were designed, which involves transition metal ions for exhibiting its own property, such as anti-microbial activity, by two steps of spin-coating method. The coating solution was prepared via click chemistry with silica precursors and mercapto functional materials. At first step of coating, the glass substrates which were coated with metallopolymer solution showed hydrophobic property, while at subsequent second step, spin-coated with the combination of 0.1 wt% of silica nanoparticles and polycaprolactone triol (psi 0.1) suspension exhibited hydrophilic property. The surface morphology and chemical compositions of the obtained coating materials were analyzed by high resolution scanning electron microscopy (HRSEM) with energy dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). The transparency and static contact angle (SCA) of coated samples were measured by UV Visible spectrophotometer and drop shape analysis system, respectively. The combination of
these features rendered our novel coating materials as anti-bacterial, anti-fog properties with extremely high scratch resistance and transparency
