| Abstract: | Preparing silver nanoparticles with dextran-ethylendiamine polymer as carrier.Firstly,the dextran-ethylendiamine polymer has been synthesized,and the polymer has been characterized by means of ultraviolet spectra and infrared spectra.Secondly,the coordination of the polymer and ion silver has been produced by the chemical synthesis,using the polymer and AgNO3 as the reactants.Thirdly,the silver nanoparticles have also been obtained from ion silver in the coordination by chemical reduction or photochemical reduction,and the silver nanoparticles have been characterized by the methods of transmission electron microscope and laser nanoparticle detecter.The silver nanoparticles with the size of 23.1 nm have been produced.It is feasible to produce the silver nanoparticles by the method mentioned in the present paper. |
