[0039] see figure 2 , the present invention at first provides a kind of synthetic method of micronano silver material, and this method specifically comprises the following steps:

[0040] 1) Dissolve silver nitrate in purified water, and stir in the dark for about 10 minutes (400-800r / min) to obtain silver nitrate solution A, the molar concentration range of which is 0.001-1.0M.

[0041] 2) Dissolve vitamin C in pure water and stir (400-800r / min) to obtain a transparent solution B with a molar concentration range of 0.003-3.0M.

[0042] 3) Dissolving gum arabic in purified water at a concentration of 2-20 wt% (weight percentage), stirring (400-800r / min) until uniform without precipitation, and obtaining gum arabic aqueous solution C.

[0043] 4) While stirring, slowly add solution B to gum arabic aqueous solution C, and continue stirring for 20 minutes until the mixture is evenly stirred to obtain solution D.

[0044] 5) Slowly add silver nitrate solution A to solution D unde...

Abstract

Provided are a micro nano silver-based material preparation method and a micro nano silver-based material. The method includes: 1) preparing a silver nitrate solution; 2) preparing a vitamin C solution; 3) dissolving Arabic gum into purified water to obtain an Arabic gum water solution; 4) slowly dissolving the vitamin C solution into the Arabic gum water solution to obtain a solution D; 5) slowly adding the silver nitrate solution into a solution D in the stirring state; 6) utilizing a centrifugal machine to conduct separation, collecting a precipitate; adding alcohol in the precipitate to conduct ultrasonic washing, conducting centrifugal separation after washing to collect the precipitate to obtain silver particles, adding deionized water into the silver particles to conduct ultrasonic washing, conducting centrifugal separation after washing and collecting maple powder to obtain the maple micro nano silver-based material. The micro nano silver-based material which is low in cost, quick in preparation process, high in yield, environmentally friendly and capable of saving energy and the micro nano silver-based material preparation method are provided.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a preparation method of a micronano silver-based material and the micronano silver-based material. Background technique [0002] Among all kinds of metal particles, silver particles with micron and nanometer sizes have attracted people's attention since their appearance, not only because of their unique electronic, optical, and catalytic properties, but also because of their good antibacterial properties and biocompatibility. And the surface is easy to modify and many other advantages. Micro-nano silver particles have been widely used in photolithography, biomedical materials, chemical catalysts, ceramic materials, conductive pastes, sewage treatment, construction materials, lubricants, light-absorbing materials, coatings, sensors, and high-performance electrode materials. [0003] In order to meet different needs, people have been exploring new methods of preparing micro-nano silver part...
