Abstract: A range of oxygen plasma treatments has been used to modify the surfaces of woven and fibrous wool samples. The resulting chemistry and composition have been characterised using X-ray photoelectron spectroscopy (XPS). The extent of oxidation of di-sulphide bonds to sulphur (S"'), in the form of sulphonic acid groups (-SO,H), by the plasma is shown to be only about 20-30 % compared to 100 % using a conventional wet chlorination process. However, the plasma does appear to react with surface carbon of …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
