Photocatalytic characteristics of TiO2 films deposited by magnetron sputtering on polycarbonate at room temperature

► Anatase TiO2 films were successfully grown at room temperature on PC substrates. ► An optimal sputtering parameters for high photocatalytic activity was proposed. ► RF power was the factor that most affected the contact angle of TiO2 films. ► The photocatalytic performance is improved by increasing RF power.
