PVD-grown antibacterial Ag-TiN fi lms on piezoelectric PVDF substrates for sensor applications

Original language description

This work reports on Ti-1 _ Ag-x(x) and Ag-TiNx electrodes deposited by dc/pulsed dc magnetron sputtering at room temperature on poly (vinylidene fluoride) (PVDF) with the purpose of developing sensors for prosthesis. In Ti-1 _ Ag-x(x) electrodes, silvercontent was varied from 0-100 at.%; and for Ag-TiNx electrodes, the nitrogen content was varied between 34 and 43 at.% and the Ti/Ag ratio changed from 12.2 to 5.2. The antibacterial activity of the samples was assessed by the agar diffusion method. Interestingly, samples from the Ag-TiNx series presented antibacterial activity, in contrast to the samples from Ti-1 _ Ag-x(x) series. XPS results showed that the as-deposited samples from the Ag-TiNx series exhibited silver clusters smaller than 4 nm. Inorder to deepen the results obtained, samples were analysed after the Halo test (antibacterial test), and XPS analyses showed the disappearance of these Ag clusters in agreement with the SEM results, which displayed a visible aggregation
