Abstract

The invention discloses a method for preparing an antibacterial medical polymer material. The method comprises the following steps: soaking a medical polymer material in a cleaning solvent for ultrasonic cleaning; then fixing the medical polymer material on a vacuum chamber treatment table of plasma equipment, and activating active groups on the surface of the medical polymer material by utilizinggas of plasma and an ultraviolet lamp; putting the activated medical polymer material into a coupling agent, and finally combining an anti-infective agent on the surface of the activated medical polymer material through chemical plating method, thereby obtaining the antibacterial medical polymer material. According to the invention, the medical polymer material is treated by combining the ultraviolet irradiation-self-assembly single-layer film and the chemical plating, and combining plasma-self-assembly single-layer film and the chemical plating; the treatment mode of the composite technologycan activate active groups on the surface of the medical polymer material to the maximum extent, so that the supply range of raw materials is further expanded, the selectivity of material selection is greatly reduced, and the limitation of the raw materials on production is minimized.

Description

technical field [0001] The invention relates to the technical field of medical polymer materials, in particular to a method for preparing antibacterial medical polymer materials. Background technique [0002] Polymer materials are materials based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Polymers are the form of life. All living organisms can be regarded as a collection of macromolecules. [0003] Polymer materials are divided into natural, semi-synthetic (modified natural polymer materials) and synthetic polymer materials according to their sources. Natural polymers are the basis for the origin and evolution of life. Human society has used natural polymer materials as means of living and production since the very beginning, and has mastered its processing technology. For example, silk, cotton, and wool ar...
