In recent years, nano Copper Hydroxide and nanotechnology have developed rapidly with their unique advantages. Nano Copper Hydroxide antibacterial material is a new type of functional material developed on the basis of nanomaterials and antibacterial materials. It has gradually become a research hotspot in the field of nanotechnology and antibacterial technology. It mainly includes the physical and chemical properties of nano Copper Hydroxide antibacterial materials and nano Copper Hydroxide antibacterial materials. Material preparation technology (nano Copper Hydroxide antibacterial powder, nano Copper Hydroxide antibacterial film, etc.), the detection of nano Copper Hydroxide antibacterial materials and the development and application of new nano Copper Hydroxide antibacterial materials.
The minimum inhibitory concentration (MIC) of copper nanoparticles was determined by the method of micro broth dilution culture. The smaller the particle size of nano copper particles, the stronger its antibacterial properties. The minimum inhibitory concentration of the synthesized copper nanoparticles is 750Mg. /L~3000Mg/L Tao Tingxian and so on. Using modified polyacrylonitrile as the matrix, nano-copper/polyacrylonitrile fibers were prepared by coordination reduction method, and their antibacterial properties against Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Streptococcus albicans were tested and compared with Non-copper polyacrylonitrile fibers were compared. It shows that the nano-copper/polyacrylonitrile has a fast antibacterial speed and an efficient bactericidal effect on gram-negative bacteria. Chen Junhua et al. used the sol-gel method to introduce copper and silver into the hexagonal mesoporous silica (HMS) of the carrier in situ, thereby obtaining a new inorganic antibacterial agent Cu with good thermal stability and ordered mesoporous structure. / Ag-HMS. It has a good antibacterial effect on Bacillus subtilis and Bacillus, and has a long-term stable antibacterial effect on Gram-positive bacteria.
The prepared nano Copper Hydroxide bulk materials are loaded on nano materials such as oxides to further reduce costs and expand the application range, such as antibacterial coatings or antibacterial ceramics. Surface modification of nano Copper Hydroxide with silane coupling agent improves the compatibility of nano Copper Hydroxide with organic media, and prepares nano composite fiber based on antibacterial polymer
With the development of technology and the growth of market demand, more and more nano Basic Copper Carbonate antibacterial materials will realize industrial production and market applications.
