Abstract
- The asymmetric wetting membranes have attracted intense attention in liquid directional transportation. However, it is a huge challenge to prepare surface layer membrane for sanitary products with antibacterial and asymmetric wettability by a simple method. Herein, the bacterial cellulose grafted with chitosan (BC-CS) was used as the hydrophilic agent to modify polypropylene nonwoven fabric (PPF) substrate via easy and effective one-sided layer-by-layer spraying to prepare the asymmetric wetting and antibacterial composite membrane (BC-CS/PPF). It showed that the BC-CS/PPF had good physical properties, which was attributed to the strong and uniform physical combination between nano-sized BC-CS and PPF. The sanitary products with BC-CS/PPF surface layer, denoted as BC-CS/PPF sanitary products, also had good absorption and anti-return property. The antibacterial test revealed that BC-CS had an excellent performance against S. aureus and E. coli in the simulated application environment. Moreover, the antibacterial performance was better than that of commercial sanitary products.<br /> (Copyright © 2021 Elsevier Ltd. All rights reserved.)
