Abstract
AgCl and PbO2 protective passivation layer on the surface of Ag nanowires (Ag NWs) were successfully fabricated by two facile methods. The as-obtained Pb2+/Ag NWs and Fe3+/Ag NWs transparent conductive films exhibited remarkable high-temperature oxidation resistance, stable optoelectronic properties, acid and alkali resistance. The sheet resistance of the Pb2+/Ag NWs and Fe3+/Ag NWs transparent conductive film could be detected even after etched by 1 M HCl and NaOH for 4 h. Furthermore, the constructing protective passivation monolayer acts as a shelter protecting the Ag nanowires from chemical and structural damage. The network structure of Pb2+/Ag NWs and Fe3+/Ag NWs transparent conductive film contact each other after the heat treatment temperature exceeds 300 ℃. The transmittance changed from 86.9 % to 81.4 % and the sheet resistance of Pb2+/Ag NWs transparent conductive film shown a smaller change trend, which verified that the film has enhanced highly. environmental stability.
