  • Publication number: 20230111046
    Abstract: A water-soluble unidirectional moisture transport traditional Chinese medicine facial mask and a preparation method thereof. The facial mask includes a facial mask substrate and a facial mask effective ingredient layer, wherein a lateral surface of the facial mask substrate is a hydrophobic surface, and the other lateral surface is a superhydrophilic surface; the facial mask effective ingredient layer is loaded to the superhydrophilic surface, in which facial mask effective ingredients include a traditional Chinese medicine colloid. In use, by simply spraying water, the effective ingredients such as the traditional Chinese medicine on the surface can be quickly dissolved to exert effects. Its hydrophobic layer can be kept dry, which not only delays volatilization of liquid and prolongs the effective time, but also is easy to operate and is clean and hygienic. The present invention has a simple preparation method, is non-harmful and non-toxic, low-carbon and environmentally friendly.

  • Publication number: 20230063352
    Abstract: 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.

  • Patent number: 10550266
    Abstract: A two-way shape memory polymer composite material is provided, which comprises two interpenetrating network polymers, wherein one polymer is a shape memory polymer made of crystalline cross-linked polymer, the other one is a cross-linked elastomeric material. The composite material is formed by interpenetration of two network polymers, wherein one network polymer will shrink under heating and the other network polymer acts as the segment for energy storage. When the first polymer network shrinks under heating, it presses the second polymer network, while the heating is cancelled the pressed second polymer network will enforce the first polymer network to recover the original shape, therefore it has the behavior of two-way shape memory.
