Segregated Network of Decorated Copper Flakes on Cellulose Fiber for Improving Thermal Conductivity of Epoxy Composites |
| 초록 |
Copper flakes decorated cellulose fibers are prepared to enhance the thermal conductivity of epoxy composites. The epoxy composites exhibits higher thermal conductivity in the vertical direction than that of the horizontal direction. The thermal conductivity of epoxy composites reaches as high as 1.4 W·m−1·K−1 at a filler content of 36.4 wt%. A theoretical model has been modified by introducing contact resistivity factor to account for the loose interconnection at the flake-flake junctions. The theoretical prediction shows that the thermal conductivity of cellulose fiber and copper flake have great impact on the heat transfer along the fiber direction. The contact resistivity factor of at the flake-flake junction has been estimated to be 0.07 m·K·W−1. *This research is financially supported from a grant of Korea National University of Transportation 2019. |
