摘要: Many properties of composite materials such as diffusion, electrical conduction, dielectric response well elasticity, are intimately related to the geometrical arrangement constitutive phases, including geometry respective interfaces. Percolation theory, whose objective is characterize connectivity in random geometries and explore them with respect physical processes, thus provides a natural frame for theoretical description composites. This article explains basic concepts static percolation theory percolative transport, which subsequently applied specific experiments on heterogeneous ionic conductors.
