Three-dimensional network aqueous gel

A three-dimensional network aqueous gel composed of a water-soluble polymer, the water-soluble polymer comprising sodium carboxymethyl cellulose, sodium alginate, and polyvinylpyrrolidone, wherein the water-soluble polymer and a solvent are crosslinked to form a three-dimensional network structure;

• wherein the water-soluble polymer comprises 10-30 wt % of sodium alginate, 10-30 wt % of polyvinylpyrrolidone, and 10-40 wt % of sodium carboxymethyl cellulose, calculated based on 100 wt % of the total weight percentage of the water-soluble polymer;
• wherein the solvent is selected from high-oxygen water and has a dissolved oxygen concentration of 25 to 35 mg/L;
• the three-dimensional network structure comprises a plurality of gel pores formed therein;
• the plurality of gel pores have a diameter of 16-18 μm and form a continuous pore structure that provides an oxygen-permeable environment with a high oxygen content;
• when applied to a wound, the three-dimensional network structure quickly forms a thin film that increases mechanical tensile properties, promotes wound healing and tissue regeneration, and has stability, transparency, and moisturizing ability.
