摘要：
We studied the nanostructure and physical properties of cellulose nanofiber-multi-walled carbon nanotube (CNF-MWNT) composite films prepared via MWNT aqueous dispersion using 4-O-methyl-alpha-n-glucuronoxylan as a MWNT dispersion aid. The composite film had high electrical conductivity (1.05 S/cm), good mechanical properties (Young's modulus: 10.1 GPa, tensile strength: 173.4 MPa) and a low coefficient of thermal expansion (7 ppm/K). FE-SEM imaging showed that the carbon nanotubes dispersed homogeneously and made reinforcing networks in the matrix of cellulose nanofibers. Improvement in the physical properties of cellulose nanofiber film by adding MWNTs is due to this composite structure. (C) 2017 Elsevier Ltd. All rights reserved.
