Structure and morphology nanocomposites based on stoichiometric polyelectrolyte complexe and metalic nanoparticles silver and copper

Abstract

Using XRD and TEM methods structure and morphogy of nanocomposites type polymer-metal based on stoichiometric polyelectrolyte complexe (chitosan-chloride and Na-phosphate of starch – starch of milk maize that Na-threepolyphospate functionalised) and metalic nanoparticles of silver and copper vere investigated. Using FTIR-spectroscopy phosphate of starch vere identificated. Nanocomposites vere formated two methods: thermo-chemical reduced of Ag+ i Cu2+ cations (by 150 °C and 170 °C accordingly) and Cu2+ cations reduced by method green synthesis (using extracte green tea) to metalic state. Show, that in volyme of nanocomposites the metalic nanopaticles silver and copper, what acquired thermo-chemicel method, have average size 5,0 nm and 3,5 nm accordingly, whereas nanoparticles copper, what acquired by method green synthesis, have average size 12,0 nm. Little size of metalic nanoparticles copper which obtaining by thermo-chemical method in contrast to nanoparticles copper which obtained by method green synthesis, caused by action of high temperature.
