Problems solved by technology

Although this chlorine dioxide gel has bactericidal properties due to the presence of chlorine dioxide, and chlorine dioxide gas can be stored in the gel, the hydrophilicity of the gel is not good, so when the chlorine dioxide gels When glue is used as a dressing and applied to the skin with a wound, it is difficult to keep the wound moist and easy to adhere to the wound tissue, which is not conducive to skin wound repair

Abstract

An antibacterial hydrogel is a hydrogel formed from a mixture, the mixture comprising: a water-soluble polymer composition, peroxidase, chlorine dioxide and water, and the water-soluble polymer composition includes polyethylene glycol And at least one selected from polyvinyl alcohol, polyacrylic acid and polymethacrylic acid. The invention also discloses a method for preparing an antibacterial hydrogel, in which polyethylene glycol and peroxidase are subjected to electrification treatment and heat treatment to obtain an intermediate product; and polyvinyl alcohol, polyacrylic acid and polyformaldehyde At least one of acrylic acid, water and chlorine dioxide are added to the intermediate product. The antibacterial hydrogel of the present invention has hydrophilicity and antibacterial properties (such as sterilizing or inhibiting bacterial growth, etc.), and is helpful for skin wound repair.

Description

technical field [0001] The invention relates to an antibacterial hydrogel, in particular to a hydrogel formed from a mixture comprising a water-soluble polymer composition, peroxidase, chlorine dioxide and water. Background technique [0002] Patent TW 201404712 in Taiwan, China discloses a chlorine dioxide gel and its preparation method. The gel is mixed with a chlorine dioxide aqueous solution and a gel formed by polyethylene glycol copolymer and bis-decyltetradecyl alcohol. Formed, chlorine dioxide gas can be stored in the gel. Although the chlorine dioxide gel has bactericidal properties due to the presence of chlorine dioxide, and chlorine dioxide gas can be stored in the gel, the gel has poor hydrophilicity, so when the chlorine dioxide gels When glue is used as a dressing and applied to the skin with a wound, it is difficult to keep the wound moist and easy to adhere to the wound tissue, which is not conducive to skin wound repair.
