Changes in wettability of carbon nanowalls (CNWs) by oxygen plasma treatment were investigated. Detailed analysis suggests that the changes in wettability of CNW from hydrophobicity to hydrophilicity by oxygen plasma treatment were mainly caused by the formation of hydrophilic nature on the CNW surface. An evaluation technique of penetration of an aqueous solution into CNW structure was also introduced in this paper. By using this technique, it was revealed that the aqueous solution penetrated into the gaps between walls for CNW samples treated by oxygen plasma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
