Antibacterial hydrogel

Abstract

The invention relates to antibacterial hydrogel. The antibacterial hydrogel consists of unsaturated polyester, dimethyl diallyl ammonium chloride, di(ethylene glycol) ethyl ether acrylate and photoinitiator, wherein the weight of the dimethyl diallyl ammonium chlorid is 1 time to 2 times of the weight of the unsaturated polyester, the weight of the di(ethylene glycol) ethyl ether acrylate is 2 times to 4 times of the weight of the unsaturated polyester, and the weight of the photoinitiator is 0.1 time to 0.5 time of the weight of the unsaturated polyester. The unsaturated polyester is initiated by methoxypolyethylene glycols, and is obtained by performing ring-opening polymerization on succinic anhydride, ethylhexyl glycidyl ether and glycidyl methacrylate. The antibacterial hydrogel disclosed by the invention is high in hydrophilicity and antibacterial performance, and long in antibacterial time.

Description

technical field

[0001] The present invention relates to prosthetic materials characterized by their functional or physical properties, and in particular to polymeric hydrogels with antibacterial properties. Background technique

[0002] Hydrogel is a polymer material with a three-dimensional network and can retain a certain amount of water. It has the characteristics of viscoelasticity, hydrophilicity, porosity, and biocompatibility. It can be used in drug delivery, wound dressing, tissue repair, and cell culture. and implanted materials. Among them, antibacterial hydrogels have potential application prospects in the fields of health, medical devices, food industry, and personal hygiene.

[0003] Currently, there are two types of preparation methods for antibacterial hydrogels. The first is to compound antibacterial agents and hydrogels, for example, mixing nano-silver with antibacterial activity or antibiotics with hydrogels. For example, Chinese patent (CN108339152A) re...
