Abstract

The degradation behavior of chitosan chains in the synthesis of Au nanoparticles by a ‘green’ method was investigated in this paper for the first time. UV–vis absorption spectra suggested the formation of Au nanoparticles and TEM images showed that their sizes were between 10 and 50 nm. During the process of synthesis, the intrinsic viscosity [η] of chitosan was observed to decrease gradually, implying that the chitosan chains degraded under the reaction conditions. Further studies showed that the degree of degradation of the chitosan chains was changed with different reaction temperatures, reactant ratios, and the molecular weights of chitosan.
