Nanofiltration Filter Paper Based on Ultralong Hydroxyapatite Nanowires and Cellulose Fibers/Nanofibers

A filter paper with a large number of nanopores and channels is vital for highly efficient nanofiltration to significantly increase the water flux without sacrificing the separation efficiency. In this work, we report a new kind of nanofiltration filter paper consisting of a cellulose nanofiber (CNF) barrier layer on the cellulose fiber (CF)/ultralong hydroxyapatite nanowire (HAPNW) substrate. The CF/HAPNW filter paper and CNF/HAPNW filter paper...
