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 cm and a pore diameter of about 500 ± 15 nm, coated with a layer of TiO anatase, with a thickness of up to 80 nm. The formation of the photocatalytically active TiO anatase phase was confirmed using Raman analysis. Coating the PET membrane with a layer of TiO increased the hydrophobicity of the system (CA increased from 64.2 to 92.4, and the antibacterial activity was evaluated using and bacteria with the logarithmic reduction factors of 3.34 and 4.24, respectively).
一种很有前景的方法是使用溶胶-凝胶法制造具有自清洁和抗菌表面的新型透气活性薄膜，该方法基于通过离子径迹技术获得的PET膜，其孔密度为10个/cm，孔径约为500±15nm，并涂覆有一层厚度达80nm的TiO锐钛矿。使用拉曼分析证实了光催化活性TiO锐钛矿相的形成。用一层TiO涂覆PET膜增加了系统的疏水性（接触角从64.2增加到92.4），并使用 和 细菌评估了抗菌活性，对数减少因子分别为3.34和4.24。
