TiO2-Polypropylene nanocomposites containing 0.5 and 1 wt% anatase TiO2 were prepared. Viscoelastic properties of the nanocomposites were investigated via dynamic mechanical thermal analysis (DMTA) before and after UV irradiation. The results reveal that the composites filled with 1wt% nano-titania show a noticeable decrease and increase in storage modulus and damping factor, respectively, indicating more photocatalytic property under UV irradiation
