Abstract: Nanotube-based thin-film composites promise significant improvement over existing technologies in the performance of large area macroelectronics, organic electronics and in bio-chemical sensing applications. In this paper, we present an overview of recent research on the electrical and thermal performance of thin-film composites composed of random 2D dispersions of nanotubes in a substrate (host matrix). Results from direct simulations of electrical and thermal transport in these composites using a finite volume method are compared to those using an effective medium approximation. The role of contact physics and percolation in influencing electrical and thermal behaviour are explored, and future research directions are discussed.
