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

Properties of TiO2 films deposited on flexible substrates using direct current magnetron sputtering and using high power impulse magnetron sputtering

“…Because of the nontoxic nature, high chemical stability, outstanding optical and electrical properties and ease of mass production, titanium dioxide (TiO 2 ) is one of the most widely used photocatalysts in many fields, such as for anti-bacterial applications, water purification devices, decomposing various organic pollutants and solar cell applications [1]. Due to wide band gap, TiO 2 has three distinct polymorphs: rutile (tetragonal structure), anatase (tetragonal structure) and brookite (orthorhombic structure) [2].…”

Polycarbonate/TiO2 nanofibers nanocomposite: Preparation and properties

“…Although there are several studies about PC‐TiO 2 system , in this work a new nanocomposite constituted by PC as polymer matrix and electrospun TiO 2 nanofibers was manufactured and analyzed by SEM, FTIR, uniaxial tensile testing, TGA and DSC. Moreover, in this paper we described the effects of the surface alteration of the TiO 2 nanofibers by [3‐(2‐aminoethyl)aminopropyl]trimethoxysilane (AMS) and the influence of this AMS functionalization on the properties and morphology of the nanocomposite.…”

Development of photocatalytic titanium dioxide membranes for degradation of recalcitrant compounds

“…The application of this method for the introduction of a built‐in catalytic functionality on filtration membranes could therefore be a suitable alternative for TiO 2 immobilization. The successful immobilization of TiO 2 by this technology has been reported in very different materials such as glass, polycarbonate, clothes, polymeric materials, among others. Its immobilization on porous ceramic materials is, however, very poor and should be explored.…”

“…Sputtering conditions have been reported to affect the structure, morphology, optical characteristics, and photocatalytic performance of TiO 2 thin films . An increase in oxygen concentration has been shown to promote a change from the amorphous to the crystalline phase while deposition time and cathode current intensity affect membrane flux .…”
