Abstract

The syntheses of silver nanoparticles stabilized by poly(allylamine) (PAA) and by polyethyleneiminated poly(allylamine) (PAA(EI)n (n = 2, 5.8)) are reported. The architectural effects in particle on the nanoparticle size, size distribution, and agglomeration behavior are determined from the UV-vis plasmon absorption band and transmission electron microscopic (TEM) analyses. The data show that PAA(EI)n display better stabilizing effects than PAA to prevent silver particles from agglomeration. Different phenomena of the polymer-protected nanoparticles at various silver ion concentrations are observed and are explained in terms of a mechanism of structure-dependent stabilization.
