Abstract: A composite includes a plastic substrate and an electrical insulator layer formed on the plastic substrate. The electrical insulator layer contains boron nitride nanotubes (BNNTs), which may be unmodified or modified BNNTS. The composite is suitable for use in making printed electronic devices. A process includes providing a plastic substrate and forming on at least a portion of a surface of the plastic substrate a layer that contains the BNNTs. A metallic ink trace is formed on a portion of the layer, such that the metallic ink trace is spaced-apart from the substrate. Using photonic or thermal sintering techniques, the metallic ink trace is then sintered.

Abstract: A molecular ink contains a silver carboxylate, an organic amine compound, an organic polymer binder, a surface tension modifier, and a solvent. The ink may be used to produce conductive silver traces on a substrate for use in fabricating electronic devices. The ink is particularly useful for producing conductive silver traces on a shapeable (e.g. stretchable) substrate in a low temperature sintering process. Also, a process for producing a conductive silver trace on a shaped substrate involves depositing the molecular ink on a shapeable substrate, drying the ink on the shapeable substrate to form a non-conductive trace containing the silver carboxylate on the shapeable substrate, forming the shapeable substrate into a shape to produce a shaped substrate so that at least a portion of the non-conductive trace is situated on a shaped portion of the shaped substrate, and sintering the shaped substrate to decompose the silver carboxylate to metallic silver thereby producing a conductive silver trace on at least the shaped portion of the shaped substrate. The process reduces potential for cracking of conductive silver traces on shaped substrates.

Abstract: A molecular ink contains: a silver carboxylate; and a polymeric binder comprising a polyester, polyimide, polyether imide or any mixture thereof having functional groups that render the polymeric binder compatible with the organic amine. Such an ink may have higher silver loading, lower viscosity and lower processing temperatures than existing silver inks.
