Abstract
- Silver nanowire (AgNW) transparent conductive films (TCFs) are expected to replace ITO films due to their high transmissivity, conductivity, and flexibility. However, there are high junction resistance and poor inoxidizability of AgNW-TCFs. Instead of sputtering a metal oxide film on the surface of AgNW-TCFs, we apply metal oxide nanoparticles (MONPs) via magnetron sputtering to modify the AgNWs network. The goal is to reduce junction resistance of wire-wire junctions while wrapping AgNWs in a manner that improves the stability of AgNWs-TCFs. SnO 2 , ZnO, Al 2 O 3 , and TiO 2 are used as modification materials, and the AgNWs@MONPs-TCF with like-core–shell structures are obtained via magnetron sputtering. The resistance of AgNWs@MONPs-TCFs is lower by about 50% than that of the reference (AgNW-TCFs). The resistance nonuniformities of the AgNWs, AgNWs@SnO 2 , AgNWs@ZnO, AgNWs@Al 2 O 3 , and AgNWs@TiO 2 TCFs are 12%–13.2%, 6.9%, 9.8%, 10.3%, and 11.1%, respectively. After 28 days, their resistance has been increased 328.2%, 18.4%, 24.3%, 24.1%, and 35.7%, respectively. At 155 °C, their non-uniformity of temperature is 35.6%, 17.7%, 16.9%, 24.8%, and 23.2%, respectively. Comparing with the reference, their failure voltage and their electric-heating efficiency have been significantly improved by MONPs modification. Using the AgNWs@SnO 2 -TCFs as a transparent heating film in electric ceramic teacups, a good electric heating effect and stable performance have presented. [ABSTRACT FROM AUTHOR]
