Abstract: In efforts to develop polymers possessing high thermal conductivity, ultra-high-molecular-weight polyethylene (UHMWPE)/boron nitride particles (BNp), UHMWPE/BN sheets (BNs), and UHMWPE/(BN+MWCNT) hybrid filler composites were analyzed in this study. Thermal conductivity was measured using the transient plane source (TPS) method. Results show that conductive pathways were formed in the composites, increasing both the connection between particles and the thermal conductivity. BNp-filled UHMWPE composites had an overall higher thermal conductivity than BNs composites.
