Facial masks cause pollution and waste resources, posing threats to the environment and health. This study developed a bioinspired dry facial mask inspired by lotus leaves, which is environmentally friendly and efficient through directional water conduction and waste reduction.
Facial masks cause huge pollution and resource waste, posing a serious threat to the ecological environment and human health. Inspired by lotus leaves, a bioinspired dry Janus all-natural facial mask (J-AFM) has been developed by a simple green-solvent-based electrospinning method. The dry J-AFM can drive water from the outside directionally to dissolve the inner nanofiber layer of nutrients quickly, while keeping the outside dry and delaying moisture evaporation. Compared with commercial wet facial masks, the dry J-AFM can reduce the total weight by 87 and 100% to avoid plastic pollution by using paper-based packaging. In addition, the waste of water and active nutrients can be reduced by 100%. The dry J-AFM with good antibacterial activity and biocytocompatibility can not only avoid the use of preservatives but also shows an obvious skincare effect. This research can trigger the reform of ecofriendly facial masks and guide the chemical industry toward sustainable and healthy development.
