Multiwall-carbon-nanotube (MWCNT)-cellulose/cellulose composite fibers with promoted mechanical and electronic activities were synthesized. Remarkably, the dispersion of MWCNTs in the composite fibers was facilitated through cellulose grafting, resulting in the tensile strength of the obtained MWCNT-cellulose/cellulose composite fibers being increased to 304.6 MPa with 10 wt% MWCNTs involved, which was almost 106.8% higher than that of pristine MWCNT/cellulose fibers with the same amount of MWCNTs. In addition, the electrical conductivity of the MWCNT-cellulose/cellulose composite fibers was enhanced to 1.3 × 10 S cm with the dispersion of 10 wt% MWCNTs, which was almost 108 times higher than that of pristine MWCNT/cellulose fibers with the same amount of MWCNTs.
合成了具有增强机械和电子活性的多壁碳纳米管（MWCNT）-纤维素/纤维素复合纤维。值得注意的是，通过纤维素接枝促进了MWCNT在复合纤维中的分散，使得含有10 wt% MWCNT的MWCNT-纤维素/纤维素复合纤维的拉伸强度提高到304.6 MPa，比含有相同量MWCNT的原始MWCNT/纤维素纤维的拉伸强度高出近106.8%。此外，在10 wt% MWCNT分散的情况下，MWCNT-纤维素/纤维素复合纤维的电导率提高到1.3×10 S cm，比含有相同量MWCNT的原始MWCNT/纤维素纤维的电导率高出近108倍。
