Abstract

We demonstrated highly transparent and flexible polytetrafluoroethylene (PTFE) passivation for the MoS₂/Ag nanowire (Ag NW) electrodes used in thin film heaters (TFHs). The electrical, optical, and mechanical properties of PTFE coated MoS₂/Ag NW electrode were compared to the bare MoS₂/Ag NW electrode to demonstrate effective passivation of the sputtered PTFE films before and after the 85 °C–85% temperature-relative humidity environment test. In addition, we investigated the performances of TFHs with PTFE/MoS₂/Ag NW as a function of PTFE thickness from 50 to 200 nm. The saturation temperature (87.3 °C) of TFHs with PTFE/MoS₂/Ag NW electrode is higher than that (61.3 °C) of TFHs with bare MoS₂/Ag NW, even after the 85 °C–85% temperature-relative humidity environment test, due to effective passivation of the PTFE layer. This indicates that transparent PTFE film prepared by sputtering process provides effective thin film passivation for the two-dimensional (2D) MoS₂ and Ag NW hybrid electrode against harsh environment condition.
