Preparation of Eco-Friendly Transparent Electrode for Flexible Device Using Cellulose Substrate

Using cellulose substrate, transparent electrode with high flexibility was fabricated to replace synthetic polymerbased electrode. The flexible cellulose substrate was prepared via the method reported in the previous study. The conductive layer of silver nanowire was deposited and fixed on the prepared substrate using spin coating process. The deposited layer was pressed at high temperature to increase the junction area. The pressed film showed transmittance higher than 80 % and haze lower than 8 %. The experimental results demonstrate that the electrode film in the study is beneficial for the development of eco-friendly films with transparency and flexibility.
