One-step alkyl-modification on boron nitride nanosheets for polypropylene nanocomposites with enhanced thermal conductivity and ultra-low dielectric loss

Polymer composites are widely used in microelectronics and wireless communication, wherein high thermal conductivity and low dielectric loss are highly pursued for efficient heat dissipation and signal transmission. However, improvement of thermal conductivity via combination of thermo-conductive additives usually accompanies with surge of dielectric loss, due to the serious interfacial polarization and phonon scattering, leading to a...
