Frequent oil spill accidents and industrial wastewater discharge has always been one of the most severe worldwide environmental problems. To cope with this problem, many fluorine-containing and high-cost materials with superwettability have been extensively applied for oil–water separation, which hinders its large-scale application. In this work, a novel human hair fiber (HHF)-polymerized octadecylsiloxane (PODS) fiber was fabricated with a facile one-pot dip-coating synthesis approach, inspired by the self-assembly performance and hydrophobicity of OTS modification. The benefits of prominent hydrophobic/lipophilic behavior lie in the low surface energy, and a rough PODS coating was rationally adhered on the surface of HHF. Driven solely by gravity and capillary force, the HHF-PODS showed excellent oil/water separation efficiency (> 99.0%) for a wide range of heavy and light oil/water mixtures. In addition, HHF-PODS demonstrated durability toward different harsh environments like alkaline, acid, and salty solutions.

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.

Controllable and reliable fabrication of wearable materials with tunable structures and integrated functionalities are urgently required for personal thermal management. Herein, this highlight presents the fabrication of MnO2 nanowires@Ag/cellulose laminated membrane with infrared insulation, antibacterial and unidirectional liquid penetration properties via orderly vacuum filtration of hydrophobic cellulose, hydrophilic cellulose and ultra-long MnO2 nanowires coated with silver (MnO2 nanowires@Ag). To do this, hydrophobic sugarcane cellulose was obtained by surface modification with silane coupling agent (A151), while hydrophilic sugarcane cellulose was obtained by HNO3 treatment. Silver coated MnO2 nanowires, as the building blocks of laminated membranes, were prepared by magnetron sputtering of silver nanoparticles onto the surfaces of MnO2 nanowires. The characterizations indicated that silver nano coating with high infrared radiation reflectivity and excellent electrical conductivity were successfully fabricated onto MnO2 nanowires surfaces, resulting in infrared insulation properties of the laminated cellulose membranes. In addition, the laminated membranes exhibit excellent unidirectional liquid penetration properties that can enhance the wearing comfort for the laminated cellulose membranes. In the antibacterial tests against Escherichia coli and Staphylococcus aureus, the laminated membranes exhibit large diameters of inhibition zones, revealing the high antibacterial activity. Moreover, excellent electrical conductivity of silver coating grants the superior Joule heating, generating rapid thermal response and uniform electrical heating at low supply voltage for extra warmth. These results indicate a promising potential of the laminated cellulose membranes for tackling personal thermal management issues related to wearable applications.
