Abstract
Flexible and transparent cellulose-indium tin oxide (ITO) layered (CITOL) films were fabricated by coating ITO nanoparticle solution on transparent cellulose films using a simple spin-coating method. Surface resistivity and transparency of the films were investigated by means of a two-point probe station and UV–Vis spectrophotometer. Electrical and optical characteristics of CITOL films strongly depend on the ITO nanoparticle concentration. The surface resistivity of CITOL films decreased whereas the optical transmittance increased with increasing the ITO concentration. The coated ITO layer was securely attached to the surface of cellulose. Details about the adhesion and characteristics of the films are illustrated. The flexible CITOL film can be used as an optoelectric material for flexible electronics and display devices.
