Abstract

The invention discloses a graphene-nano-silver composite material which comprises the following components in parts by weight: 1-16 parts of graphene mixed powder and 1-9 parts of nano-silver anti-microbial powder; the graphene mixed powder comprises the following components in parts by weight: 0.3-65 parts of graphene, 0.2-25 parts of graphite carbon and 0.02-10 parts of graphite; and the nano-silver anti-microbial powder comprises the following components in parts by weight: 2-5 parts of silver nitrate, 90-95 parts of zirconium phosphate and 1-5 parts of zinc oxide. The composite material has excellent anti-microbial sterilizing effects and stable properties. The invention also discloses a preparation method for the composite material, the steps are few and the process is simple. Besides, the invention also discloses an antibacterial fiber adopting the composite material and the preparation method thereof, and meanwhile, the antibacterial fiber is applied to a blended yarn. The inhibition ratios of the antibacterial fiber to escherichia coli, staphylococcus aureus and Candida albicans all exceed national standard.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a graphene-nano-silver composite material and its preparation method and application. Background technique [0002] Due to its good broad-spectrum antibacterial properties, low toxicity to human cells, low drug resistance and high safety, silver nanoparticles have been gradually used in biomedicine and clinical and other related fields. All kinds of antibacterial, sterilizing life and medical supplies such as materials, gynecological antibacterial lotion, etc. have appeared on the mass consumer market. [0003] As a brand-new material, graphene has excellent properties in electricity, optics, heat, mechanics and other aspects due to its novel structure, which has attracted the attention of researchers since its discovery. Combining this new type of material with polymer materials has shown more possibilities for technological innovation in various industries. [000...
