چکیده انگلیسی:
In this work, carbon nanotube (CNT) based nanocomposites with high mass fraction are proposed by
in-situ bridging carbon matrix into CNT paper through optimized chemical vapor infiltration (CVI).
Nanoinfiltration behavior of CNTs is basically investigated under the CVI process. The contact between
each CNT can be strengthened and the conductive pathways can be established, resulting in the better
mechanical and electrical properties. Compared with the pristine CNT paper, the CNT/C composite after
pyrolysis process confirms a remarkable advance in tensile strength (up to 310 ± 13 MPa) and Young’s
modulus (up to 2.4 ± 0.1 GPa). Besides, a notable feature of electrical conductivity also shows an improvement up to 8.5 S/cm, which can be attributed to the mass fraction of CNT (41 wt%) breaking the limits of
percolation thresholds and the efficient densification of this sample to establish the conductive pathways.
This study has a broad application in the development of the multi-functional electrical and engineering
materials.
