Silver Doped Boron Nitride Approach to Improve the Thermal Conductivity of Polyurethane Composites

High thermal conductivity composites have attracted considerable attention due to their extensive applications in electronic devices. In the present work, we propose a novel strategy by employing boron nitride doped silver nanoparticles (BN-Ag) to improve the thermal conductivity of polyurethane composites. The BN-Ag composite was prepared by depositing silver nanoparticles (AgNPs) onto the surface of boron nitride (BN), facilitating cross-linking between adjacent BN sheets. Interestingly, despite the low concentration of AgNPs at just 2.5
