3D structure of carbon nanotubes for highly thermal conductivity of epoxy composites |
| 초록 |
A novel method to prepare the 3D structure of multi-walled carbon nanotubes (CNTs) and form the thermally conductive pathways to enhance the thermal conductivity of CNTs based epoxy composites even the low content of filler. PMMA beads were used as template to disperse the silane functionalized carbon nanotubes (sCNTs) following the electrostatic interaction method. The improvement of thermal conductivity of epoxy composites were from 0.19 W/mK to 0.96 W/mK as the presence of the sCNTs increases to 1 wt%. The well dispersion of sCNTs at the interstitial space between PMMA beads and epoxy matrix were the main factor for the effective formation of the long-range phonon transfer lead to reduce the interfacial phonon scattering and improve thermal conductivity. The method developed in this work introduces a new approach of using non-conductive polymer beads as constituting element in conductive formation. This research was supported by Korea National University of Transportation in 2018. |
