Thermal conductivity of a surface modified graphene oxide-carbon nanotubes hybrid composite |
| 초록 |
Surface modified graphene oxide (GO)-multi-wall carbon nanotube (MWCNT) composite materials were fabricated by casting method. The polar interactions between the functional groups of GO and MWCNT allowed high thermally conductive materials.When the total amount of composite was fixed while changing the amount of MWCNTs, a maximum thermal conductivity was obtained with the addition of about 0.5 wt% of MWCNTs in the filler. Measured thermal conductivity was higher than pristine GO and MWCNT composite value and decreased for MWCNT concentrations above 0.5%. The increased thermal conductivity was due to the formation of 3-D heat conduction paths by the addition of MWCNTs. Too high a MWCNT concentration led to increased phonon scattering, which in turn led to decreased thermal conductivity. The measured storage modulus was higher than that of the pristine composite because of the aggregation in these materials. |
