We demonstrate a novel method of creating highly electrical conducting films comprising silver/polyelectrolyte multilayer (PEM) complexes. Ag/PEM complexed films have been prepared by concentrated incorporation of Ag nanoparticles within the ionically complexed films of linear polyethylenimine and poly(acrylic acid) through the repetitive procedures of cationic exchange and reduction reaction. The resulting Ag/PEM films are observed fairly good electrical conductivity that is slightly lower than that of bulk Ag by a factor of one order. In addition, the hybridized films can be micro-patterned with photolithographic process. Notably, loading and unloading of Ag nanoparticles from the complexed films is systematically controlled by varying the concentration and time of etching process. Finally, mechanical tests for flexible conducting films are carried out in view of foldability, bendability, fatigue-enduring and Stretchability capability. |
