Abstract

The invention belongs to the technical field of macromolecular functional materials, and particularly relates to a cosmetic bionic polymer membrane as well as a preparation method and application thereof. The preparation method comprises the following steps: (1) sequentially adding first polydimethylsiloxane PDMS1, second polydimethylsiloxane PDMS2, a cosmetic active component, microgel and an emulsifier, carrying out uniform mixing, and then adding a catalyst to obtain a uniform emulsion precursor; and (2) adding a coalescing agent into the precursor, transferring the formed mixture into a film tool, vacuumizing the film tool, and conducting standing at room temperature for 24-30 hours to obtain the cosmetic bionic polymer film. According to the invention, polydimethylsiloxane containing Si-H bonds and polydimethylsiloxane containing C=C bonds are subjected to a hydrosilylation addition reaction under the action of the catalyst, so the polydimethylsiloxane better conforms to the characteristics of young skin, and the bionic property and cosmetic property of the polymer film are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer functional materials, and in particular relates to a biomimetic polymer film for beauty and its preparation method and application. Background technique [0002] The skin covers the whole body, and it protects various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. However, the skin is inevitably damaged by aging, environmental damage and certain diseases, and diseases characterized by skin barrier dysfunction are still prevalent in the population. Skin dehydration is clinically observed as chronic inflammation and pruritus. Skin aging, whether chronological or accelerated by sun exposure, causes some degree of distress; as skin ages, it loses its biomechanical integrity and is also more susceptible to environmental damage and wound healing degree will be damaged. [0003] Age-related changes in the mechanical integrity of the skin primarily res...
