Embodiment 1

[0074]Stir 12 grams of absolute ethanol and 12 grams of oleic acid evenly, add 20 milliliters of an aqueous solution containing 0.680 grams of calcium nitrate tetrahydrate and 24.7 milligrams of silver nitrate, after stirring well, add 20 milliliters of aqueous solutions containing 1.000 grams of sodium hydroxide and 10 ml of an aqueous solution containing 0.420 g of sodium dihydrogen phosphate dihydrate. The resulting mixture was transferred to a reaction kettle, sealed, heated to 180° C., and kept at this temperature for 24 hours. The obtained product is washed several times with ethanol and water to obtain nano-silver composite hydroxyapatite ultra-long nanowires. Nano-silver composite hydroxyapatite ultra-long nanowires were dispersed in 100 ml of water, poured into a sand core funnel, filtered with a vacuum pump, and dried at 95°C for 3 minutes to obtain nano-silver composite hydroxyapatite ultra-long nanowires with a thickness of 82 microns. Antibacterial paper with lon...

The antibacterial paper has bactericidal effect, the main component of the antibacterial paper is hydroxyapatite super-long nanowire with a length of 10-1000 micrometers, a diameter of 5-100 nanometers and a length-diameter ratio of greater than 300, the antibacterial paper also includes nano-silver particles that are uniformly immobilized on the hydroxyapatite super-long nanowire and has a particle size of 3-100 nanometers. The antibacterial paper has a thickness of 50-200 micromters. The nano-silver compounded hydroxyapatite super-long nanowire antibacterial paper has the efficacy of rapid, efficient and broad spectrum antibacterial efficacy.

Description

technical field [0001] The invention belongs to the field of antibacterial nanometer materials, and relates to a highly flexible nanometer antibacterial paper, in particular to a nanosilver composite hydroxyapatite superlong nanowire antibacterial paper. Background technique [0002] Bacteria and fungi are ubiquitous, and bacterial infection and transmission have always been a major factor affecting human health and longevity. Common "refrigerator syndrome" in daily life is caused by harmful bacterial infection. After clinical operation, intensive care is needed to prevent a series of complications caused by bacterial infection. As people's awareness of health and safety increases, the demand for products related to antibacterial materials is also increasing. [0003] According to the chemical composition, antibacterial materials are divided into organic antibacterial agents, inorganic antibacterial agents and natural antibacterial agents. Many of these organic antibacter...
