Cellulose is one of the most abundant organic compounds in earth. Therefore, it can be employed as an eco-friendly and sustainable material in a wide range of applications. Especially, cellulose nanocrystals (CNCs) that have a length of several hundred nanometers have been investigated in many research fields owing to their various excellent characteristics. However, there are only few reports on the use of CNCs in organic semiconductor devices. Thus, CNCs are very promising material that can exhibit useful properties in electronic devices. In this study, we fabricated organic resistive switching devices using a mixture of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) conducting polymer and CNCs. The PEDOT:PSS-CNCs mixture film was inserted between ITO and MoO3/Al electrodes. The change in current density-voltage curves by various concentrations of CNC in PEDOT:PSS were measured and the electrical parameters of PEDOT:PSS and PEDOT:PSS-CNCs devices were compared. In addition, the electronic structure of PEDOT:PSS-CNC film was determined using X-ray photoelectron spectroscopy. Through these results, we discuss the mechanism of resistive change by CNCs.
