The present work is concerned with studying the electrical and dielectric
properties of a single, binary, and ternary nanocomposite of Mn3O4 (M), TiO2
(T), and reduced graphene oxide (RGO). The electrical properties of the investigated systems were studied via dc-, ac- conductivity, dielectric, and impedance
spectroscopy (EIS) measurements. The electrical conductivity is found to
increase in the following order: rGO [T@rGO [Ti [ M@rGO [M@T [
M@T@rGO [M. The dielectric constant (e0
) and dielectric losses (e00) values of
all materials showed a monotonous decrease with an exponential behavior by
increasing the applied ac. Frequency. At constant frequency and temperature,
the e0 value followed the order: TiO2[ rGO [ T@rGO[ M@rGO[ M@T [
M@T@rGO [M, whereas, the e00 value followed the order: T@rGO [T [
rGO [ M@rGO[ M@T [ M@T@rGO[ M. The results obtained were
explained and discussed.
