The films made of carbon nanotubes have the potential of next generation transparent conducting film (TCF) due to high conductivity, mechanical flexibility, and abundance of raw carbon materials. TCF have been studied for use as transistors, electrode in photovoltaics and organic light-emitting diodes, sensors, and actuators. These applications generally require high transparency and low electrical resistance. In this study, we investigated thermal behaviour of TCF made of multi-walled carbon nanotubes (MWCNTs). The TCF was fabricated by using the spray coating method. Before coating, the solution was prepared in deionized water with 0.02wt% sodium dodecyl sulphate and 0.02~0.04 wt% MWCNTs and sonicated for several hours. The temperature increase of TCF was obtained with decreasing electrical resistivity. The morphology of the TCF, the effect of applied voltage and the amount of MWCNTs on the thermal behaviour were investigated. |
