Formatıon Of Copper Nanoclusters In The Presence Of Poly(Allyl Amıne)-Poly(Acrylıc Acıd) Complexes

Abstract

Metal nanoclusters that are synthesized via chemical, thermal or ionizing radiation reduction of metal ions need stabilizing agent to prevent oxidation and coagulation. In this study, copper nanoclusters (Cu0) were synthesized in poly(allyl amine) (PAlAm) and poly(acrylic acid) (PAA) matrices by ionizing radiation (gamma and X-rays) reduction of copper ions (Cu2+) and stabilized in polymers. Ionizing radiation was chosen because of not requiring reducing chemicals, providing a reduction with high selectivity and purity. Complexation of copper ions with polymer matrices were characterized by using UV-visible spectroscopy and the size of complex coils were determined by dynamic light scattering (DLS).
