Abstract

The invention relates to an anti-bacterial high polymer material and a preparation method and application thereof. The anti-bacterial high polymer material is derived by cyanuric chloride, contains menthol side groups and has an anti-bacterial effect. The anti-bacterial high polymer material is synthesized through condensation polymerization of a diamino compound and two helium atoms in a polymerizable monomeric compound derived by the cyanuric chloride. The anti-bacterial high polymer material has an efficient anti-bacterial effect, the cost is low, the structure is simple, and preparation iseasy. The anti-bacterial high polymer material can be widely used in industries of sanitation or environment protection or medical treatment.

Description

technical field [0001] The invention belongs to the technical field of synthesis of functional polymer materials, and relates to an antibacterial polymer material and its preparation method and application, in particular to an antibacterial polymer material based on a polymerizable monomer derived from cyanuric chloride and its preparation method and application application. Background technique [0002] In recent years, the resistance of multiple antibiotics has spread all over the world, and the hospital infection control of medical devices has attracted more and more attention from people in the field. However, traditional antibacterial methods have certain drawbacks. First, leachable fungicides, such as antibiotics and heavy metals, are incorporated into polymer surface coatings and gradually released over time. Long-term use increases the resistance of microorganisms to antimicrobial agents and produces drug-resistant bacteria, so the preparation It is particularly urg...
