탄소 나노튜브-전도성 고분자 복합체 기반 하이브리드형 투명 전극의 특성 분석

Abstract

This study demonstrates the properties of hybrid-type transparent electrodes, which have been made using the mixture of carbon nanontubes (CNTs) and conductive polymers, for touch screen panels. The CNTs have been deposited on glass and PET substrates via spray coating and then coated with thin PEDOT:PSS polymer films on the CNTs via spin coating. For all of the samples, the surface and cross-sectional morphologies, sheet resistances, visible transmittances, chromatic properties have been characterized as functions of their preparation conditions. Also, the sheet resistances and surface morphologies of several CNTs and hybrid specimens have been measured before and after bending test. The experimental results confirm that the hybrid-type films can satisfy all of the requirements that are required for transparent, flexible electrodes of touch screen panels.
