Synergistic effects of polymethylmethacrylate beads and sintering of copper nanoparticles on thermal properties of polycarbonate composites |
| 초록 |
We introduce a simple method to improve the thermal conductivity of polycarbonate (PC) composites by synergistic effects of segregated network of formic acid-treated Cu nanoparticles (NPs) and polymethylmethacrylate (PMMA) beads. The surface-treated Cu NPs, PMMA beads and PC pellet were mixed using injection machine at 280 °C and the Cu/PMMA/PC composites were prepared by using extruder machine. The thermal conductivity, and thermal stability of the PC composites were investigated. The significant improvement of the thermal of PC composites was attributed to segregation of the Cu NPs between PMMA beads. At 30 wt% of Cu NPs, the thermal conductivity of the PC composites was 1.2 W/mK in the presence of 30 wt% of PMMA beads. This research was supported by Korean National University of Transportation in 2018. |
