摘要： Flexible and stretchable electronics, including supercapacitors and pressure sensors, are made using carbon nanostructures produced by providing a first composite structure which includes a temporary substrate and an array of carbon nanotubes arranged in a stack on a surface of the temporary substrate such that the stack of carbon nanotubes is oriented generally perpendicular to the surface of the temporary substrate, which may include silicon dioxide. The stack of carbon nanotubes is transferred from the temporary substrate to another substrate, which includes a curable polymer, thereby forming another composite structure comprising the stack of carbon nanotubes and the cured polymer.

摘要： Technologies are generally described for an electron conductive polymer capacitor may incorporate a conductive polymer mixture embedded with carbon nanoparticles between electrodes to rapidly charge and store large amounts of charge compared to conventional electrolytic capacitors. Such a capacitor may be constructed with a laminate sheet including layers of inner and outer electrodes, an electrolyte mixture between the electrodes, a conductive polymer mixture, and a composite mixture of carbon nanoparticles embedded in the conductive polymer between the inner electrodes. The laminate sheet may be wound into a roll and the inner and outer electrodes are coupled electrically. When an electric field is applied, cations within the electrolyte mixture move towards the outer electrodes and anions towards the inner electrodes. Further, the inner conductive polymer layer is ionized causing electrons to move toward the inner electrodes to be deposited onto high surface area carbon nanoparticles where charge is stored.
