Studies on PMMA-co-PBA-TiO2 Nanocomposite Films

S. Radhika Kathyayini, S. Sangeetha and M. Sridharan    

Abstract: The polymer based nanocomposites were obtained by merging inorganic Titanium Dioxide (TiO2) in the polymer system focusing on raising the optical transparency and to study the photo catalytic activity. The precursor chosen here is titanium (IV) isopropoxide which is the starting material for sol-gel synthesis to form a TiO2 sol-gel solution. The choices of the polymers are acrylates namely methyl metha acrylate and butyl acrylate monomers which are copolymerized using benzoyl peroxide as initiator for enhanced copolymerization. This study involves synthesis of TiO2 sol-gel solution and developing TiO2 thin films coated over glass slides by spin coating technique to improvise the transmittance efficiency characteristic of glass. The deposited thin films were characterized for their structural, morphological, optical properties besides the elemental composition and photo catalytic activity. The prepared films were highly transparent were hydrophobic. The PMMA-co-PBA-TiO2 nanocomposite films exhibited good photo catalytic activity.
