Abstract
This paper describes the possibility of using a mixture of nitrogen (N2) and xenon (Xe) at different volume concentration for bioresorbable electrospun poly-(l-lactic) acid (PLLA) scaffolds surface modification by reactive DC magnetron sputtering of a titanium target. It was observed that the selected technological modes do not reliably affect the morphology of scaffolds and simultaneously, increased their hydrophilicity. Moreover, the results of the X-ray photoelectron spectroscopic investigation show that the composition of the thin film coating consists mainly of compounds of titanium oxides (TixOy) and titanium oxynitrides (TiOxNy) and slightly depend of gas ratio. In another hand, C-O and C=O ratio depends of concentration of Xe and decreases with its increasing.
