Figure 4From: Large-surface-area BN nanosheets and their utilization in polymeric composites with improved thermal and dielectric propertiesDielectric and thermal conductive properties of polymeric composites. (a) Frequency-dependent dielectric constants of blank PMMA and PMMA/BN composites. (b) Increased dielectric constant (taken at 106 Hz) and thermal conductivity with increasing BN fraction in PMMA/BN composites. Blue curve is the fitting to experimental points using the Agari model; red one is the upper limit of thermal conductivities in theory from a parallel model.Back to article page
