Reversible Formation of Silver Clusters and Particles in Polymer Films

چکیده
The photoinduced formation of silver (Ag) clusters and particles in poly(vinyl alcohol) poly(acrylic acid) blend films is described. The photoreduction 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 photoreduction. This paper describes the process for generating these films and provides results from the initial investigation into the formation and decay process observed.

In the present work, we report the synthesis and characterization of silver nanoparticles, capped with chitosan (biopolymer ). The majority of the particles produced in this way had sizes around 18 nm. Composite films of capped silver nanoparticles and chitosan polymer were studied to understand the charge transport under different pressure. Films of different compositions were prepared to meas...
متن کاملAtmospheric-Pressure Plasma Reduction of Metal Cation-Containing Polymer Films to Produce Electrically Conductive Nanocomposites by an Electrodiffusion Mechanism
We describe an atmospheric-pressure plasma process for the reduction of metal cation-containing polymer films to form electrically conductive patterns. Thin films of poly(acrylic) acid (PAA) containing silver ions (Ag) were prepared by mixing the polymer with silver nitrate (AgNO3) in solution to produce a cross-linked precipitate, homogenizing, and depositing onto a substrate by doctor’s blade...
