Synthesis of Ultralong Copper Nanowires for Enhanced Thermal Conductivity of Poly(methylmethacrylate) Composites |
| 초록 |
We synthesized CuNWs by reducing Cu2+ via glucose in the presence of oleylamine and oleic acid in an aqueous solution The thermal conductivity of poly(methylmethacrylate) (PMMA)/CuNWs composites was improved at low loading fractions of CuNWs. CuNWs have the average length of 200±13 µm and a mean diameter of 105±4 nm. The thermal conductivity of the PMMA composites reached the highest value of 0.85 W·m-1·K-1 at 2.0 wt% of CuNWs loading, which showed an enhancement of more than 400% as compared to that of the neat PMMA. The significant improvement of thermal conductivity is attributed to the well-dispersed CuNWs in the PMMA matrix and the high aspect ratio of CuNWs. The elongation strain at failure and toughness of the PMMA composites were significantly increased with increasing contents of CuNWs, and the volume resistivity of the PMMA composites was remained to be greater than 1010 Ω·m.. *This study was supported by Korea National University of Transportation 2019. |
