In the present work, polymer-silica hybrid latexes based on methyl methacrylate (MMA), butyl acrylate (BuA), 2-hydroxyethyl methacrylate (HEMA), and different inorganic precursors (tetraethoxysilane (TEOS), isobutyltriethoxysilane (IBTES), diethoxydimethylsilane (DEDMS), vinyltriethoxysilane (VTES)) were synthesized by emulsion polymerization and sol-gel process. The resulting latexes were characterized both as materials placed into plastic vials and as films deposited onto clean glass slides by various techniques including Fourier transform infrared (FT-IR), UV?vis spectrometry, thermal analysis (TGA) and water contact angles of film surfaces. The results showed that the surface wettability was changed from hydrophilic to hydrophobic by adding a precursor with vinyl organic group. For all hybrid latexes, the Si-O-Si groups give a strong absorption band in the spectral region between 1200-1000 cm-1 (asymmetric stretching vibration), which confirms the formation of a network structure inside the films. The antireflective films, due to diffuse reflection, have been given by the preparation from inorganic precursors.
