dcterms.abstract | This invention involves fabric-supported chitosan modified temperature responsive PNIPAAm/PU hydrogel and the use thereof in preparation of facial mask. The merit of this invention is the hydrogel formed can reversibly swell and deswell near body temperature; the incorporation of PU can suppress the syneresis of PNIPAAm at an elevated temperature; Grafting of PNIPAAm and PU onto the surface of cellulose fabrics can enhance the mechanical strength of hydrogel; Coupling of chitosan to the surface of hydrogel can not only improve the handle and skin affinity, but also render the facial mask antibacterial; The hydrogel is capable of loading a variety of nutrients (or other functional components), which can release at body temperature; the hydrogel facial mask can be reusable with repeated rinsing. | - |
