The invention discloses a mirror surface antifogging material, which is prepared from the following raw materials: a perfluoro solvent, perfluoropolyether and an adhesion auxiliary agent, and the adhesion auxiliary agent is polymethyl methacrylate and / or poly (hydroxyethyl methacrylate). The mirror surface anti-fog material is suitable for visual reflectors such as glass mirror surfaces, silver mirrors and aluminum mirrors, a transparent nano hydrophobic film can be formed on the mirror surfaces through simple spraying at normal temperature, the light transmittance of the formed film layer is high, and the mirror surface anti-fog material has the advantages of clear vision, long anti-fog time, fast film forming, no peculiar smell, simple operation and the like, and is suitable for popularization and application. The anti-fog mirror can be applied to articles such as bathroom mirrors, cosmetic mirrors, glasses and the like in daily life.

The application provides an ultrasonic response piezoelectric ionic hydrogel and application thereof, and the hydrogel is formed by cross-linking and solidification of a precursor solution under ultraviolet irradiation; components of the precursor solution include a photosensitive polymer, an ionic polymer, a photoinitiator and a solvent; the photosensitive polymer includes any one or a combination of at least two of polyether F127 diacrylate, polyhydroxyethyl methacrylate, polyethylene glycol dimethyl acrylate, methacrylated gelatin or methacrylated collagen; and the ionic polymer includes any one or a combination of at least two of epsilon-polylysine, polyethyleneimine hydrochloride, polyallylamine hydrochloride, polyquaternary ammonium salt-10 or cationic guar gum. The application uses ultrasonic waves as an external remote driving signal to non-invasively and painlessly activate the piezoelectric ionic effect of the hydrogel, generate detectable periodic voltage and current signals in the hydrogel, and has excellent treatment effect on acne and infected wound repair.

The application belongs to the technical field of hydrogel preparation, and discloses a glutamine-induced injectable hydrogel and a preparation method thereof, which comprises a sodium alginate hydrogel of a hydroxyethyl methacrylate matrix, a crosslinking agent and an initiator; and the preparation raw materials of the sodium alginate hydrogel of the hydroxyethyl methacrylate matrix comprise hydroxyethyl methacrylate, sodium alginate, L-glutamine and anhydrous magnesium chloride. The polyhydroxyethyl methacrylate which is anti-swelling, stable and has good biocompatibility is used as the hydrogel matrix, L-glutamine is used for inducing rapid gelation and removing active oxygen and activating cells, and a physical and ionic crosslinking network formed by sodium alginate and magnesium ions is introduced, so that a stable vaginal support material which is injectable, anti-swelling and mechanically strong and tough is prepared.

The application belongs to the technical field of kitchen utensils, and discloses a non-stick pot plate manufacturing process and a non-stick pot plate. The non-stick pot plate manufacturing process comprises the following steps: predefining a pattern, etching treatment, bottom oil non-stick coating spraying treatment and surface oil non-stick coating spraying. The preparation process of the bottom oil non-stick coating comprises the following steps: mixing water, glycerol, nano iron oxide, polytetrafluoroethylene, silane coupling agent, polyhydroxyethyl methacrylate, sodium dodecyl benzene sulfonate and water-based hydroxyl acrylic resin, adding lysine diisocyanate, and forming the bottom oil non-stick coating. The preparation process of the surface oil non-stick coating comprises the following steps: mixing water, nano silicon nitride, silane coupling agent, sodium dodecyl benzene sulfonate, polyhydroxyethyl methacrylate, polytetrafluoroethylene and amino resin, adding triethylenetetramine, and forming the surface oil non-stick coating. The concave-convex patterns on the inner surface of the non-stick pot plate form multiple heating zones. The non-stick coating layer on the surface of the non-stick pot plate has good adhesion, wear resistance and impact resistance.
