"Temperature dependence of thermal conductivity enhancement in single-walled carbon nanotube/polystyrene composites." Applied Physics Letters 96(8): 083105-083105.0003-6951http://dx.doi.org/10.1063/1.3323095http://hdl.handle.net/10222/36157The thermal conductivity of single-walled carbon nanotube (SWCNT)/polystyrene composites, prepared by a method known to produce a uniform distribution of SWCNT bundles on the micrometer length scale, was measured in the temperature range from approximately 140 to 360 K. The thermal conductivity enhancement (50% for 1 mass % at 300 K) is reasonably constant above room temperature but is reduced at the lower temperatures. This result is consistent with the expected, large contribution of interfacial thermal resistance in SWCNT/polymer composites. Enhancements in electrical conductivity show that 1 mass % loading is in the region of the electrical percolation threshold.article968083105
