摘要: Surface-wave plasma has been used to modify polymer surfaces. The density and selectivity of the functionalizations are very important for biomaterial applications. Low-temperature treatment successfully applied many types polymers generate functional In this study, we focus on surface modification amino groups chitosan surfaces by ammonia treatment. Chitosan is a nontoxic, biocompatible biodegradable polymer, which promotes scarless healing skin through embolization. experimental results X-ray photoelectron spectroscopy measurements showed that exposure increased nitrogen incorporation from 4.67 9.92%. group (–NH2/N) 53.7 78.4% after irradiation.
