    摘要: A new class of electrochemical capacitors provides in its charged state a positive electrode including an active material of a p-doped material and a negative electrode including an active material of an n-doped conducting polymer, where the p-doped and n-doped materials are separated by an electrolyte. In a preferred embodiment, the positive and negative electrode active materials are selected from conducting polymers consisting of polythiophene, polymers having an aryl group attached in the 3-position, polymers having aryl and alkyl groups independently attached in the 3- and 4-positions, and polymers synthesized from bridged dimers having polythiophene as the backbone. A preferred electrolyte is a tetraalykyl ammonium salt, such as tetramethylammonium trifluoromethane sulphonate (TMATFMS), that provides small ions that are mobile through the active material, is soluble in acetonitrile, and can be used in a variety of capacitor configurations.

    摘要: The present invention comprises an apparatus for and method of creating electrically modifiable images using a computer printer. In one embodiment, one or more ink reservoirs of a printer cartridge are filled with an electrochromic ink. The printer thus prepared can be used to print electrochromic patterns on a surface using standard ink application methods. In certain embodiments, more than one ink reservoir is filled with electrochromic ink. In these embodiments, separate reservoirs are filled with separate ink formulations so that the characteristics of the electrochromic pattern can be varied.

    摘要: The present invention describes an improved method for the polymerization of &agr;,&agr;-dihalo-p-xylene's such as the &agr;,&agr;′-dihalo-2-methoxy-5-(2-ethylhexyloxy)-xylene's. The procedure for synthesis is based on the specific order of addition of reagents and the use of an anionic initiator that allows control of the molecular weight of the polymer. The molecular weight control allows processability of the polymer which is important for its utility in applications including in light-emitting-diodes, field effect transistors and photovoltaic devices.
