Herein, we report the synthesis of two dimensional, flake-like nanostructures of polyaniline and their nanocomposites in an epoxy matrix with different particle loadings. An anomalous enhancement in the dielectric constant is observed for the synthesized nanocomposites due to the 2D flake-like structure of the polyaniline fillers at room temperature over the wide AC frequency range of 1 Hz to 107 Hz.
