Electrophoretic deposition of carbon nanotubes on heat spreader for fabrication of thermal interface materials (TIM)

Thermal interface materials (TIMs) are applied in packaging of electronic devices for heat dissipation purposes. Carbon nanotubes (CNTs) are promising material due to their high thermal conductivity properties which will give optimum performance as TIMs. In this research study, electrophoretic depos...
