摘要：

Membranes with high separation efficiency and antibacterial functions are promising candidates for drinking water intake during emergency events. Herein, we report a simple filtration process to prepare silver nanoparticle decorated cellulose nanofibrous (CNFs) membrane. These CNFs were prepared via 2,2,6,6-tetramethylpiperidine-1-oxyl oxidation process. Ag/CNFs composite nanofibers were fabricated by an in situ reduction method. After filtering Ag/CNFs composite dispersion on a macroporous support, a 710-nm thick Ag/CNFs membrane with Ag loading amount of 3.6 wt% was formed, which presents 86% rejection for 5-nm nanoparticles from water with flux of about 1000 L m(-2) h(-1) bar(-1). In addition, this membrane shows excellent antibacterial ability. This membrane holds potential for field water treatment during emergency events. (C) 2017 Published by Elsevier Ltd.
