Abstract
The invention relates to nano-silver particles and preparation thereof. The preparation of nano-silver particles comprises the following steps: according to the volume ratio of (100:1)-(1:1), mixing 0.01-1 g/L thymol solution with 0.01-100 g/L silver nitrate solution, stirring for 10-600 min at a constant speed at 30-80 DEG C to obtain a nano-silver colloidal solution, repeatedly cleaning with ethyl alcohol and deionized water, and centrifuging and drying to obtain the nano-silver particles. According to the invention, thymol is adopted as a reducing agent and a stabilizer, and the advantages of simple technology, moderate reaction and environmental protection are achieved. The prepared nano-silver is used in the textile field to prepare a textile which has multiple efficacies of fragrance, anticorrosion, sterilization, mite killing, skin nosomycosis and tinea prevention, so that the added value of the textile is greatly increased.
Description
Technical field
The invention belongs to field of nanometer material technology, particularly a kind of nano-Ag particles and preparation thereof.
Background technology
In recent years, nanometer technology has become the cutting edge technologies interdisciplinary such as physics, chemistry, biology, medical science and material science, because having the tremendous influence that cannot estimate to the energy, medical science, electronics, aircraft industry etc. and enjoying the concern of researcher.And metal nanoparticle causes great interest because having unique character such as physics, chemistry, optics, electricity, magnetics, calorifics, biology, metal nanoparticle especially Nano Silver has huge potential using value in multiple field, as sensing technology, optical device, catalysis, biomarker, medicine reprinting and treatment of cancer etc.
The preparation of traditional Nano Silver is divided into Physical and chemical method.Physical requires higher to instrument and equipment, and producing cost is expensive.Chemical method many employings hydrazine hydrate, formaldehyde, polyalcohol, organic amine etc. make reducing agent, although these reducing agents have high activity, to bad environmental, and obtained Nano Silver easily agglomeration occurs.
In recent years, green, environmental protection, efficient and cheap method is adopted to prepare the focus that Nano Silver becomes research gradually, compared to physics, chemical method advantageously, wide material sources, reaction condition is gentle, just can react at normal temperatures and pressures, the nano silver particles of synthesis has good biocompatibility.The green reducing agent adopted at present mainly comprises: vitamin, natrium citricum, pyrogallol, hydroquinones, Tea Polyphenols, glucose, fructose, sucrose, plant and pericarp extract, microorganism etc.
Thymol (thymol), another name thymol, thymol, flaky crystal, is very easily dissolved in ethanol, ether, acetic acid, chloroform and benzene.Naturally be present in labiate Thymus plant, there are pungent perfume (or spice) and the hay-scented fragrance of Thymus plant, be phytovolatilization main body of oil (containing about 50%), available sodium phenolate method is out isolated from plant volatile oil, more namely drying, decompression distillation obtain product.Thymol can be used as flavorant, anticorrisive agent medically and bactericide.Thymol has very strong acaricidal action, and the solution 24h of 1% solution death rate half an hour 100%, 0.03% kills 100%.
Chinese invention patent 201310291305.8: adopt suitable, the trans-3-(2 of anti-mite active matter 3-benzene chloro benzyl (IRS) that anti-mite textile is conventional; 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester prepares Nano Silver as protective agent; Nano Silver can be made to realize the double effects of antibacterial and anti-mite, and the antibiosis anti-acarien Complex Function being suitable for textile arranges simultaneously.But Permethrin is mainly used in low toxic pesticide, may be used for various pests on control cotton, vegetables, tealeaves, fruit tree, be particularly suited for the control of sanitary insect pest, be not suitable for the textile of Long Term Contact human body skin.And it still needs to adopt the one in sodium borohydride, potassium borohydride, hydrazine hydrate, vitamin C, reproducibility glucose to carry out reducing nano-silver as reducing agent.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, aim to provide a kind of nano-Ag particles and preparation thereof.
The present invention is achieved by following technical proposals:
According to the volume ratio of 100:1-1:1, the thymol solution of 0.01-1g/L is mixed with the liquor argenti nitratis ophthalmicus of 0.01-100g/L, under the temperature conditions of 30 DEG C-80 DEG C, average rate stirs 10-600min, obtain nano-class silver colloidal solution, repeatedly clean by ethanol and deionized water, centrifugal, at 80 DEG C, after vacuum drying 1-24h, obtain nano-Ag particles.
The present invention has following beneficial effect:
The present invention adopts thymol as reducing agent and stabilizing agent, possess that technique is simple, reaction temperature and, the advantage such as environmental protection.The Nano Silver prepared is used for field of textiles, can prepare to have fragrance, anticorrosion, sterilization, except mite, the textile preventing the multi-efficiencies such as the sick and ringworm of skin fungus, substantially increase the added value of textile.
