Claim 16:
17. A method of forming EMI shielding structures, comprising:
forming a conductive composition that comprises:
a polymer;
fully exfoliated single sheets of graphene that are present as a three-dimensional percolated network within the polymer;

forming rectangular EMI shielding panels that each comprise a first end and a second end by applying the conductive composition to a side of a substrate to thereon form a conductive layer, the substrate is planar and flexible, the substrate comprises one or more of a film or a fabric;
affixing a pair of rectangular EMI shielding panels orthogonal to each other at their first ends;
successively overlapping the pair of rectangular EMI shielding panels over each other to thereby form a plurality of interconnected EMI shielding planes; and
affixing the pair of rectangular EMI shielding panels to each other at their second ends to thereby form a helical EMI shielding (“HES”) structure that unfolds to an unfolded state and folds to a folded state along its center axis, the plurality of interconnected EMI shielding planes are each angularly offset from each other about the center axis to form a helical structure when in the unfolded state, the plurality of interconnected EMI shielding planes each rotate about the center axis when the HES structure transitions between the folded state and unfolded state.
