Abstract:
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 10–7 cm−2 and a pore diameter of about 500 ± 15 nm, coated
with a layer of TiO2 anatase, with a thickness of up to 80 nm. The formation of the photocatalytically
active TiO2 anatase phase was confirmed using Raman analysis. Coating the PET membrane with a
layer of TiO2
increased the hydrophobicity of the system (CA increased from 64.2 to 92.4, and the
antibacterial activity was evaluated using Escherichia coli and Staphylococcus aureus bacteria with the
logarithmic reduction factors of 3.34 and 4.24, respectively).
