Breathable Films with Self-Cleaning and Antibacterial Surfaces Based on TiO<sub>2</sub>-Functionalized PET Membranes
A promising approach that uses the sol–gel method to manufacture new breathable active films with self-cleaning and antibacterial surfaces is based on the PET membranes obtained via ion track technology with a pore density of 10<sup>–7</sup> cm<sup>−2</sup> and a pore diamete...

| description | A promising approach that uses the sol–gel method to manufacture new breathable active films with self-cleaning and antibacterial surfaces is based on the PET membranes obtained via ion track technology with a pore density of 10<sup>–7</sup> cm<sup>−2</sup> and a pore diameter of about 500 ± 15 nm, coated with a layer of TiO<sub>2</sub> anatase, with a thickness of up to 80 nm. The formation of the photocatalytically active TiO<sub>2</sub> anatase phase was confirmed using Raman analysis. Coating the PET membrane with a layer of TiO<sub>2</sub> increased the hydrophobicity of the system (CA increased from 64.2 to 92.4, and the antibacterial activity was evaluated using <i>Escherichia coli</i> and <i>Staphylococcus aureus</i> bacteria with the logarithmic reduction factors of 3.34 and 4.24, respectively). |
