چکیده انگلیسی
Highly conductive and strong composite fibers based on cellulose and multiwalled carbon nanotube with multiple hydrogen bonding moiety (MWCNT-MHB) were manufactured via a facile organic solvent-based solution spinning. The microstructure, molecular interaction, mechanical and electrical properties of the composite fibers were investigated as a function of MWCNT-MHB content (0.5-30.0Â wt%). The FT-IR spectra of the composite fibers revealed the existence of the specific interaction between cellulose backbone and MWCNT-MHB via hydrogen bonding. The MWCNT-MHB was dispersed uniformly in the cellulose fiber matrix, which was confirmed by SEM images of the cross-section and longitudinal surfaces for the composite fibers. Accordingly, the composite fibers with different MWCNT-MHB contents exhibited high performance in tensile mechanical properties such as tensile strength of 156-278Â MPa, failure strain of 3.7-7.0%, and initial modulus of 11.3-13.9Â GPa. In addition, the electrical conductivity of the composite fibers increased significantly from â¼10â8Â S/cm to â¼100Â S/cm with the increase of the MWCNT-MHB loading from 0.5Â wt% to 30.0Â wt%, particularly at a certain MWCNT content between 0.5 and 1.0Â wt%. The composite fiber with 30.0Â wt% MWCNT-MHB, which has high electrical conductivity of 2.7Â S/cm and tensile modulus of â¼12.5Â GPa, could be thus used for electrically conductive wire and electric heating element for smart textiles.
