Problems solved by technology

[0003] Complexing agents are used in the treatment of heavy metals to control metal ions. However, the existing complexing agents have poor complexing ability and cannot meet the demand.
In addition, some metals have excellent antimicrobial effects, such as silver, zinc, copper, etc. However, due to the special properties of metals, their application in the field of antibacterial is limited. For example, the use of silver in antibacterial textiles will easily lead to the gradual dimming of product color

Abstract

The invention discloses a polymer containing a heterocyclic structure. The polymer is formed by polycondensation or copolymerization of a monomer containing the heterocyclic structure. The polymer hasexcellent complexing ability to metals, can effectively remove heavy metals, can improve the antibacterial effect and significantly reduce the discoloration phenomenon when used in cooperation with antibacterial metals, further expands the application range of the polymer and the antibacterial metals, and has broad development prospects.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polymer containing a heterocyclic structure and its application. Background technique [0002] Heavy metal, refers to the density greater than 4.5g / cm 3 Heavy metals, including gold, silver, copper, iron, mercury, lead, cadmium, etc., accumulate to a certain extent in the human body, which will cause chronic poisoning, and will also accumulate in water and soil, and then biomagnify in the food chain It will affect the entire biosphere and cause great harm. [0003] Complexing agents are used in the treatment of heavy metals to control metal ions. However, the existing complexing agents have poor complexing ability and cannot meet the demand. In addition, some metals have excellent antimicrobial effects, such as silver, zinc, copper, etc. However, due to the special properties of metals, their application in the field of antibacterial is limited. For example, the use of silver...
