    Description

    This paper reports a facile one-pot method to produce graphene oxide nanocellulose composite (GNCC) that was subsequently reduced using L-ascorbic acid to form a conductive paper (CP). Cellulose fbers were directly added into the reaction system during graphite exfoliation using sulfuric acid to produce cellulose nano- or microfbrils through acid hydrolysis along with mechancial mixing. FTIR and Raman analyses indicated that reduction using L-ascorbic acid efciently produced a welldeoxygenated CP with high conductivity of 116.3±1.5 S m−1 at 20% graphene oxide loading. Furthermore, the presence of cellulose nano- or microfbrils improved CP thermal stability with onset degradation Tonset of 319 °C as well as mechanical properties with a specifc tensile of 19 N mg−1. This one-pot method substantially simplifed the GNCC production process and has practical signifcance.
