Study on Water Bath Pulling Method Mechanism for Implementing the Equidistant Arrangement of - Ag NWs on Flexible Substrate

Recently, Ag NWs have attracted great attention as the functional layer of flexible and transparent devices. The quality of Ag NWs network is a precondition for the conductivity and transmittance in practical applications. In this paper, we demonstrate the mechanism of water bath pulling method for preparing a transparent conductive film with a two-layer vertical directional silver nanowire network on the flexible transparent PDMS substrate that was applied to resistive sensor. The resistive sensor showed a high transmittance (87.2%), a low sheet resistance (26.9 Ω/sq) and a fast response (GF=90.3) at the tensile strain of 30%. These outstanding performances demonstrate its potential for human motion monitoring.
