Stability Effect of Silver Nanoparticle Colloid

Article Preview

Abstract:

To solve the existent stability difficulties in the long term storage of the silver nanoparticle hydrocolloids (AgNPs) , this paper makes a comprehensive investigation on the effects of different synthetic methods which influence the stability of AgNPs. The controlled AgNPs are prepared by two kinds of precursors: silver diamminohydroxide ([Ag (NH3)2]OH ) and silver nitrate (AgNO3 ) respectively precursors;in addition the stability of the AgNPs hydrocolloid is studied by UV-vis; A discovery was found after contrast :the particle sizes of the [Ag (NH3)2]OH precursor based AgNPs hydrocolloid are more uniformed,well controlled and of better dispersibility.this kind of AgNPs exhibits higher stability compared to the AgNO3 precursor based AgNPs hydrocolloid.
