Abstract:The main purpose of this study is to verify the excellent absorption efficiency of polyacrylonitrile (PAN) foam which has a hierarchically aligned porous structure similar to wood for water purification. Ice template and freeze drying method was employed to prepare the PAN foam, and the performance of the prepared sample was characterized by advanced technology. Experimental data revealed that the micromorphology, absorption efficiency, and mechanical properties were tunable by controlling the polymer concentr… 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.
