Deposition of amino-rich coatings by RF magnetron sputtering of Nylon: Investigation of their properties related to biomedical applications

Abstrakt
Stability of amino-rich films of plasma polymers in aqueous environments is investigated in this study. It is found that the solubility of the coatings is strongly dependent on the working gas mixture: while the films prepared in Ar/N2 mixtures are relatively stable in an aqueous environment, much faster dissolving and roughening of the films deposited using N2/H2 gas mixtures was observed, which limits their applicability in the biomedical field.
Moreover, it was found that chemical changes of the coatings are not significantly different for samples immersed into water or stored on open air.
