ABSTRACTDielectric relaxation phenomena have contributions from both the internal reorientation modes of the molecules comprising a material as well as the details of how those modes couple together to form the material. This behavior can change quite sensitively with changes in the composition of material. For a composite material that has more than one phase, the presence of phase boundaries and even shape can play an additional and large role in the observed relaxation behavior. Analysis of the relaxation spectra can be used to study these effects. Examples are shown, primarily of polymeric materials, ranging from liquid solutions to phase separated mixtures to show how dielectric relaxation over a wide frequency range can be used to characterize and study composite materials.
