1. A laminate comprising:
at least two electrically-conductive layers comprising a first electrically-conductive layer and a second-electrically conductive layer, wherein the first electrically-conductive layer and the second electrically-conductive layer each comprise at least 90% by weight of copper; and
at least two electrically-insulative layers comprising a first electrically-insulative layer and a second electrically-insulative layer, wherein the first and second electrically-insulative layers are coupled by one or more adhesive layers to the first electrically-conductive layer and the second electrically-conductive layer, respectively; wherein the first electrically-insulative layer is coupled to the second electrically-insulative layer by an additional adhesive layer, and wherein the first and second electrically-insulative layers each comprise an organic polymeric aerogel,
wherein at least a portion of a front surface of the laminate is defined by the first electrically-conductive layer; and
wherein at least a portion of a back surface of the laminate is defined by the second electrically-conductive layer.
