摘要:
Polymer nanofibers, such as polyaniline nanofibers, with uniform diameters less than 500 nm can be made in bulk quantities through a facile aqueous and organic interfacial polymerization method at ambient conditions. The nanofibers have lengths varying from 500 nm to 10 µm and form interconnected networks in a thin film. Thin film nanofiber sensors can be made of the polyaniline nanofibers having superior performance in both sensitivity and time response to a variety of gas vapors including, acids, bases, redox active vapors, alcohols and volatile organic chemicals.

摘要:
Disclosed is a hybrid electrochemical cell with a first conductor having at least one portion that is both a first capacitor electrode and a first battery electrode. The hybrid electrochemical cell further includes a second conductor having at least one portion that is a second capacitor electrode and at least one other portion that is a second battery electrode. An electrolyte is in contact with both the first conductor and the second conductor. In some embodiments, the hybrid electrochemical cell further includes a separator between the first conductor and the second conductor to prevent physical contact between the first conductor and the second conductor, while facilitating ion transport between the first conductor and the second conductor.

An interconnected corrugated carbon-based network comprising a plurality of expanded and interconnected carbon layers is disclosed. In one embodiment, each of the expanded and interconnected carbon layers is made up of at least one corrugated carbon sheet that is one atom thick. In another embodiment, each of the expanded and interconnected carbon layers is made up of a plurality of corrugated carbon sheets that are each one atom thick. The interconnected corrugated carbon-based network is characterized by a high surface area with highly tunable electrical conductivity and electrochemical properties.

摘要:
Capacitors having electrodes made of interconnected corrugated carbon-based networks (ICCNs) are disclosed. The ICCN electrodes have properties that include high surface area and high electrical conductivity. Moreover, the electrodes are fabricated into an interdigital planar geometry with dimensions that range down to a sub-micron scale. As such, micro-supercapacitors employing ICCN electrodes are fabricated on flexible substrates for realizing flexible electronics and on-chip applications that can be integrated with micro-electromechanical systems (MEMS) technology and complementary metal oxide semiconductor technology in a single chip. In addition, capacitors fabricated of ICCN electrodes that sandwich an ion porous separator realize relatively thin and flexible supercapacitors that provide compact and lightweight yet high density energy storage for scalable applications.
