Reversible Formation of Silver Clusters and Particles in Polymer Films

Abstract

The photo induced formation of silver (Ag) clusters and particles in poly(vinyl alcohol) poly(acrylic acid) blend films is described. The photo reduction of the Ag+ is achieved by subjecting the Ag+ doped films to 350 nm photons. The formation of Ag clusters and particles is monitored using UV-VIS spectroscopy. Films treated with H2O2 exhibit bleaching of the UV-VIS signals corresponding to Ag clusters and Ag particles that were generated during the photo reduction. This paper describes the process for generating these films and provides results from the initial investigation into the formation and decay process observed.
