Dielectric Properties and Thermal Conductivity of Polyvinylidene Fluoride Synergistically Enhanced with Silica@Multi-walled Carbon Nanotubes and Boron Nitride

There is an urgent need for polymer composites with high thermal conductivity and electrical insulation in microelectronic packaging.Due to their fascinating chemical and physical properties, multi-walled carbon nanotubes (MWCNTs) have enabled major achievements in polymer composites fields as a reinforcement filler.Nevertheless, high conductivity of raw MWCNTs (R-MWCNTs) was an obstacle to wider application of the CNTs in some special fields, which require outstanding thermal conductivity and insulation properties simultaneously.In this work, silica@MWCNTs were prepared to reduce the electrical conductivity.The composites
