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.
