1. A process, comprising:
providing a plastic substrate;
forming on at least a portion of a surface of the plastic substrate a layer comprising boron nitride nanotubes (BNNTs);
forming a metallic ink trace on a portion of the layer comprising BNNTs, such that the metallic ink trace is spaced-apart from the plastic substrate by the layer comprising BNNTs; and
sintering the metallic ink trace using photonic or thermal sintering techniques,
wherein the BNNTs are modified BNNTs selected from polymer-wrapped BNNTs and BNNTs coated with a ligand or a surfactant.
