Rice material receives the favor of people as a kind of new material, and nanoscale science and technology becomes the leading skill for also becoming this century
Art.On the other hand, most of metal ion is able to suppress the activity of bacterium, removes the heavy metal ion being harmful to the human body, silver
The bactericidal effect of grain is most strong, and most study is the antibacterial agent containing Argent grain at present.Therefore, nano silver material becomes everybody and grinds
The focus studied carefully.
The small-size effect and skin effect of nano-Ag particles are significant, have very strong penetration power and antibacterial activity.Its
Safety, antibiotic property, persistence, heat resistance etc. have advantage, therefore obtain widely in biological medicine, anti-biotic material
Using.Currently, the preparation of nano silver is broadly divided into physical method and chemical method: physical method needs to use laser, electron beam irradiation etc.
The nano silver particle size of method, preparation is more uniform, but technology is complicated, equipment requirement is high；Chemical method be by reduction silver from
Son obtains nano silver, easy to operate, cost is relatively low, but partial size is not easily controlled, and the nano-Ag particles of synthesis are unstable, easy group
It is poly-.
In research field, the more of nano silver preparation is chemical reduction method, specifically includes that Brust-
Schiffrin method, template, surface ligand induced corrosion method, microemulsion method, electrochemical process and Microwave-assisted synthesis method.These
Method requires that certain reducing agent and stabilizer is added, and most reagent is all toxic.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of nano silver gel fluorescent solutions, the material non-toxic and do not have to
Extraly add reducing agent and stabilizer.
The technical scheme adopted by the invention is that a kind of preparation method of nano silver gel fluorescent solutions, by polyacrylamide
Amine aqueous solution and silver nitrate solution mixing, ultraviolet light irradiation is reacted under dark surrounds, and it is molten to obtain nano silver gel fluorescence
Liquid.
The features of the present invention also characterized in that
The volume ratio of polyacrylamide solution and silver nitrate solution is 500:3-100:1.
The concentration of polyacrylamide solution is 0.3-0.55g/ml.
