| Abstract:In this study, micron-sized hexagonal boron nitride (h-BN) with varying plate diameters were used as thermal conductive fillers and incorporated into aramid paper matrix. By combining wet-forming technology with hot-pressing process, the composite aramid paper was successfully prepared. The thermal conductivity, insulation performance, and mechanical properties of the composite aramid paper were systematically tested to investigate the synergistic effects of h-BN with different plate diameters and the mechanisms underlying the enhancement of the composite aramid paper’s performance. The results showed that combining large-diameter-sized h-BN and small-diameter-sized h-BN in a mass ratio of 1∶1 resulted in mix-diameter-sized h-BN (M-BN) ; when the M-BN addition amount was 30%, the prepared composite aramid paper M-BN-30 exhibited in-plane and through-plane thermal conductivities of 9.754 and 0.171 0 W/(m·K) at 25 ℃, respectively, representing increases of 11.1% and 59.7% compared to the original aramid paper. Furthermore, the breakdown strength of M-BN-30 increased to 14.82 kV/mm, with a 33.3% improvement over the original aramid paper. Additionally, M-BN-30 exhibited low dielectric constant and dielectric loss factor values of 3.25 and 0.025 9, respectively. |
