INTENSE PULSED LIGHT WELDING PROCESS WITH SIMULTANEOUS MECHANICAL ROLL-PRESSING FOR HIGHLY CONDUCTIVE SILVER NANOWIRE/POLYETHYLENE TEREPHTHALATE COMPOSITE ELECTRODE

초록

In this study, an intense pulsed light (IPL) welding process and mechanical roll-pressing method were employed to enhancing performance for the silver nanowire/polyethylene terephthalate (AgNW/PET) composite electrode. The conditions of two processes were optimized to maximize welding and embedding of AgNWs. Scanning electron microscope (SEM) analysis was conducted to investigate the welded and embedded AgNW network. The surface roughness of AgNW/PET composites were observed and evaluated using atomic force microscope (AFM). The optical properties (transmittance and haze) of AgNW/PET composites were measured by UVvis spectrometer. The AgNW composite electrode with IPL irradiation and roll-pressing showed a high electrical conductivity, high transmittance, and a reduced surface roughness. Finally, heating film based on AgNW/PET composite electrode was successfully operated showing stable performance.
