Review of thermal conductivity in composites: Mechanisms, parameters and theory

This article reviews theoretical and experimental aspects of thermal conductivity in composites, from thermal energy generation to heat transfers. The fundamental mechanism of thermal conduction, its mathematical aspects, and certain essential parameters to be considered in this study, such as crystallinity, phonon scattering, or filler/matrix interfaces are discussed in detail to examine their impact on thermal conductivity, complementing several reviews in the field.
