Abstract:In this article, polytetrafluoroethylene (PTFE) microporous membranes with excellent tensile strength and good wear durability were successfully fabricated by the addition of nano-alumina (Al2O3). The friction and mechanical behavior of PTFE microporous membranes with different nano-Al2O3 contents were investigated by Martindale abrasion tester, dynamic mechanical analysis, and universal testing machine. Scanning electron microscopy was applied to analyze the surface, longitudinal section, and worn surface of … 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.
