Abstract :

 The current study report the effects of the addition of 0.1, 0.5, 1.0, 1.5 and 2.0 wt.% protic polyethyleneimine and aprotic poly(sodium 4–styrene sulfonate) polymers in producing different colors of AgNPs solution. The kinetic study was monitored by time–dependent surface plasmon resonance bands in the UV–vis region and by analysing the data obtained from absorption peaks of UV–vis spectra. The results revealed that a wide range of colors can be perfectly tuned by means of fine control of the polyethyleneimine and poly(sodium 4–styrene sulfonate) concentrations. The possible mechanisms that contributed to the changing of AgNP’s color are proposed.
