Abstract:To obtain superior performance in adhesion, polyvinyl chloride (PVC) substrates were modified by excimer laser direct writing with different operating wavelengths, scanning speeds, and laser fluences. The induced morphological and electrochemical changes were detailedly tested and analyzed. Microchannels were formed on the surfaces of the PVC substrates due to the laser ablation, where the melted-resolidified droplet-like structures were distributed uniformly and can significantly improve the mechanical interl… Show more
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.
