In order to enhance the miscibility between the inorganic and the organic phases,the silanol coupling agent is made from the slane VTMS and the colloid silica. Then the silanol coupling agent and nano-particles of ZnSb2O6 as the conductive filler are successfully bonded and the nano-particles of ZnSb2O6 will become more organic-like. The colloid silane-SiO2-ZnSb2O6 precursor solution is subsequently mixed with a homogeneous lsopropylalcohol solution of SR-399 acrylic monomers (Dipentaerythritol pentaacrylate) and the active free radical agent709. Under nitrogen purging, this reaction solution prepolymerize at 60℃. Then, the solution is spin-coated with the spin coator at room temperature. At last, the coated thin film is cured and crosslinked by the UV curing reactor to form the highly transparent thin film with good optoelectronic properties from hybrid organic-inorganic nano-composite.
