Method for preparing transparent and conducting sheets on polymers

摘要

A method is proposed for preparing transparent and conducting sheets on polymers. A vertical structure is formed stacked on a polymer base depositing a transparent coating of indium oxide doped with tin (ITO) to provide a suitable substrate for optoelectronic applications. The ITO electrode has a preferential crystalline orientation on the plane (111). The formation of this film improves the physical properties of the substrate, reaching a high transparency value, an average of close to 80% in the 400-1100 nm spectra range, and conductivity, sigma > 10<3> ( OMEGA xcm)<-1>. The ITO films manufactured by the method proposed do not require heating of the substrate during the preparation of the layer, or treatment after deposition, to obtain high optoelectronic quality. The use of a pre-treatment with plasma of the organic sheets lead to obtaining adherent films without damaging the polymer sheets.
