preparation example Construction

[0022] The invention discloses a method for preparing a composite bacteriostatic material based on cyclodextrin copper, wherein the composite material is composed of cyclodextrin copper and a surfactant.

[0023] Preparation of β-cyclodextrin copper: first prepare 10mL of a solution containing 0.5mol / L NaOH and 0.02mol / L β-cyclodextrin, then add 15mL of 0.04mol / L CuSO to the solution 4 ·5H 2 O solution, rapidly forming Cu(OH) 2 Blue precipitate, after stirring at room temperature for 24h, remove Cu(OH) by suction filtration 2 solid particles; then add 200mL absolute ethanol to the filtrate, when the blue precipitate gradually appears in the solution, it is filtered after standing for 48h, the gained blue precipitated solid is washed with ethanol and a small amount of distilled water, and vacuum-dried at room temperature to obtain The blue solid powder is β-cyclodextrin copper.

Embodiment 1

[0024] Example 1: Preparation of β-cyclodextrin copper complex solution containing 0.3% PVP.

[0025] First prepare 5mL 3.14×10 -3 mol / L of the β-cyclodextrin copper solution prepared above, add 0.015g PVP to the solution, and mix well to obtain a β-cyclodextrin copper compound solution containing 0.3% PVP.

Embodiment 2

[0026] Example 2: Preparation of β-cyclodextrin copper complex solution containing 0.1% PVP.

[0027] First prepare 5mL 3.14×10 -3 mol / L of the β-cyclodextrin copper solution prepared above, add 0.005g PVP to the solution, and mix well to obtain a β-cyclodextrin copper compound solution containing 0.1% PVP.

Abstract

The invention relates to a preparation method of a composite bacteriostatic material based on cyclodextrin copper. Firstly, cyclodextrin copper is prepared; then the cyclodextrin copper solid is ultrasonically oscillated in water, gradually dissolved, and then a surfactant is added to obtain cyclodextrin copper. Compound solution of copper dextrin and surfactant. In the present invention, a surfactant with high biological safety is mixed with cyclodextrin copper, and the two produce a synergistic effect, so that copper ions are fixed on the cavity port of cyclodextrin to reduce the freeness of copper ions. Dextrin copper can significantly improve the antibacterial ability of cyclodextrin copper against Escherichia coli and Staphylococcus aureus, and the inhibitory effect of the compound solution on Staphylococcus aureus, Escherichia coli and Candida albicans has reached a high level.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a method for preparing a cyclodextrin copper-based composite antibacterial material. Background technique [0002] Bacteria are tiny living organisms that can grow and multiply rapidly under suitable conditions. Some of them can cause food to spoil and deteriorate, and may cause human disease through contact, ingestion, etc., and pose a relatively large risk to human life and health. . Since the invention of antibiotics in the last century, it was once considered to be a good solution to bacterial problems. However, with the extensive use of synthetic antibiotics, the problems of environmental pollution and antibiotic resistance of bacteria have gradually become prominent. The development of green and pollution-free antibacterial Materials have become a research hotspot. [0003] Antibacterial materials are broadly classified into organic antibacterial materials...
