The present invention discloses a unidirectional moisturizing nanofiber facial mask substrate with asymmetric wettability and preparation thereof. The preparation includes: preparing a superhydrophilic electrospun fiber membrane on a substrate by electrospinning; preparing a hydrophobic electrospun fiber membrane by electrospinning on a lateral surface of the superhydrophilic electrospun fiber membrane away from the substrate to form a double-layered membrane; and removing the substrate, and drying the double-layered membrane to obtain the asymmetric unidirectional moisturizing facial mask substrate with one side being superhydrophilic and the other side being hydrophobic. The superhydrophilic layer can absorb a nutrient solution and be applied to the skin surface, while the hydrophobic layer can keep itself dry, reduce the consumption of the nutrient solution and inhibit volatilization of the nutrient solution. The process is simple, uses readily available materials, and is non-toxic, environmentally friendly, and low-cost, thus solving several key problems with current commercial facial mask substrates.
