Abstract
Controllable and reliable fabrication of wearable materials with tunable structures and integrated functionalities is urgently required for personal thermal management. Here, MnO2 nanowires@Ag/cellulose laminated membranes with infrared insulation, antibacterial, and unidirectional liquid penetration properties assembled were fabricated by hydrophobic cellulose, hydrophilic cellulose, and ultralong MnO2 nanowires@Ag in vacuum filtration and magnetron sputtering methods. The results indicated that nanosilver coating with high infrared radiation reflectivity and excellent electrical conductivity was successfully fabricated onto MnO2 nanowire surfaces, resulting in infrared insulation properties of the laminated cellulose membranes. In addition, the laminated membranes exhibit unidirectional liquid penetration properties that can enhance the wearing comfort. In antibacterial tests against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, the high antibacterial activity is revealed. These results indicate the promising potential of the laminated cellulose membranes for tackling personal thermal management issues related to wearable applications.
