ABSTRACT
This chapter presents a full model for the evaluation of the electromechanical response of a graphite nanoplatelet (GNP)-based nanocomposite for possible application as a smart thermal interface materials (TIM) in electronic/nanoelectronics. S. Hung et al. studied heat transport in polymer nanocomposites reinforced with GNPs using high-precision thermal conductivity measurements. The chapter explores a full electromechanical model of a TIM made of a GNP nanocomposite for integrated stress monitoring of electronic devices. The electrical transport in GNP-based nanocomposites is described applying the tunneling percolation model. A critical issue concerns the characterization of the GNP electrical conductivity, which strongly depends on the set of parameters used during the thermal expansion of Graphite intercalation compounds. The direct current electrical conductivity of nanocomposites with different concentrations of GNPs was measured applying the four-wire volt-amperometric method. J. Yu et al. reported an efficient process for converting natural graphite into few-layer GNPs.
