Investigation of Silver Nanowire Transparent Heated Films Possessing the Application Scenarios for Electrothermal Ceramics

As transparent heated films (THFs) based on conductive oxides (TCOs) are restricted by expensive raw materials and inappropriate fabricating film curved surfaces because of its brittleness, silver nanowires (AgWS-TCF) is an ideal alternative material for THF. However, there still many problems to be solved in the electrical thermal stability AgNWs-TCF. In this paper, Al-doped ZnO (AZO) nanoparticles produced magnetron sputtering was used modify coat AgNWs network, ceramic /AgNWs@AZO-TCF obtained. Compared with ceramic/AgNWs-TCF, sheet resistance ceramic/AgNWs@AZO-TCF decreased from 53.2 19.3 Ω/sq, non-uniformity 18.0% 7.0%, inoxidizability, current-impact resistance, failure voltage increased significantly. addition, electrothermal efficiency significantly improved after a SiO2 layer surface substrate. ceramic/AgNWs@AZO-TCF, temperature ceramic-SiO2/AgNWs@AZO-TCF increases 78.7 113.2 °C under applied 6 V, which possess application scenarios electrothermal-ceramics teacup (or tableware) realize function heat preservation disinfection.
