▎ 摘　　要

Rice straw nanofibers (RSNF) with high lignin content were used in making nanocomposites with graphene oxide (GO) at loading ratios from 0.625% to 5% (based on weight of RSNF). The prepared RSNF/GO films were characterized regarding their tensile strength, equilibrium moisture content (EMC), and electrical properties. Microstructure of the films was examined using scanning electron microscopy (SEM). Addition of 2.5% of GO resulted in increasing tensile strength and Young's modulus by 33.5% and 21.5%, respectively. Presence of GO significantly reduced moisture sorption of the films. Electrical conductivity measurement showed significant increase in permittivity (epsilon ') upon increasing GO loading. The ionic conductivity value of films containing 5% of GO was 10(-7) S cm(-1), which is acceptable value for use as antistatic and/or dissipated films. The electrical properties of the prepared low-cost high-lignin-content RSNF/GO films could have potential use in flexible electronic applications such as in energy harvesting and storage.
