The structure of the hybrids resulted dominated by the structural features of HKUST-1 but a uniform incorporation of graphene-like layers was found. dc experiments, confirmed the insulating character of HKUST-1 and revealed that the incorporation of graphene-like layers drastically changes the conductivity of hybrids.
