Antibacterial and ultraviolet protective neodymium-doped TiO2 film coated on polypropylene nonwoven fabric via a sputtering method

A neodymium-doped titanium dioxide film was coated on polypropylene nonwoven fabric via a magnetron sputtering method to prepare multifunctional textiles with antibacterial and ultraviolet protective properties. The antibacterial property of the single-layer titanium dioxide film coated sample was better than that of the single-layer neodymium film coated sample. And that of the three-layer film coated samples was better than that of the double-layer film coated samples, which the latter also was superior to that of the single-layer film coated samples. A longer deposition time of the titanium dioxide film increased the antibacterial rate. The hydrophilicity of the coated samples was improved by ultraviolet irradiation, which improves the catalytic antibacterial ability. The ultraviolet protective factor of the sample that absorbs more ultraviolet is higher, and the water contact angle after ultraviolet irradiation decreases. This improves antibacterial performance. A titanium dioxide film doped with neodymium was improved without any significant change to the morphology and luster of the samples. This can lead to further applications of the coated polypropylene non-woven fabric with good antibacterial properties.

Automated summary

A neodymium-doped titanium dioxide film was coated on polypropylene nonwoven fabric to prepare multifunctional textiles with antibacterial and ultraviolet protective properties. The antibacterial performance was improved in samples with multiple layers of film coatings, while ultraviolet irradiation enhanced hydrophilicity and catalytic antibacterial ability. Samples with higher ultraviolet absorption had better ultraviolet protective factors and improved antibacterial performance. The morphology and luster of the samples remained unchanged with the addition of neodymium-doped titanium dioxide film, allowing for further applications in antibacterial-coated polypropylene non-woven fabric.
