We report the synthesis of copper nanowires (CuNWs) and the enhanced thermal conductivity of poly(methylmethacrylate) (PMMA) composites at low-loading fractions of CuNW. The scanning electron microscope, X-ray diffractometer, thermal diffusivity meter, high-resistance meter, universal testing machine, and thermogravimetric analyzer were used to investigate the properties of CuNW/PMMA composites. The elongation strain to failure, toughness, and thermal stability of the PMMA composites significantly increased with increasing contents of CuNW. The CuNW/PMMA composites showed the thermal conductivity and volume resistivity of 0.85 W/mK and 7×1010Ω·m, respectively, at 2.0 wt% of CuNW. 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 experimental results of thermal conductivity fitted well with the Agari model. [ABSTRACT FROM AUTHOR] |
