Electrically conductive articles are provided, including a composite including (a) a resin, and (b) electrically conductive shaped particles distributed in the resin, the particles having a monosized distribution. Each particle has a shape including at least a first surface and a second surface intersecting the first surface at an angle a between about 5 degrees and about 150 degrees. The composite has a thickness and often each of the electrically conductive shaped particles distributed in the resin is oriented within the resin such that the particle does not extend beyond the thickness of the composite. A method for making an electrically conductive article is also provided, including (a) providing electrically conductive shaped particles having a monosized distribution, and (b) distributing the particles into a resin to form a composite.
