Abstract: Certain example embodiments of this invention relate to large-area transparent conductive coatings (TCCs) including carbon nanotubes (CNTs) and nanowire composites, and methods of making the same. The ?dc/?opt ratio of such thin films may be improved via stable chemical doping and/or alloying of CNT-based films. The doping and/or alloying may be implemented in a large area coating system, e.g., on glass and/or other substrates. In certain example embodiments, a CNT film may be deposited and then doped via chemical functionalization and/or alloyed with silver and/or palladium. Both p-type and n-type dopants may be used in different embodiments of this invention. In certain example embodiments, silver and/or other nanowires may be provided, e.g., to further decrease sheet resistance. Certain example embodiments may provide coatings that approach, meet, or exceed 90% visible transmission and 90 ohms/square target metrics.

Abstract: A method of manufacturing a high surface area per unit weight carbon electrode includes providing a substrate, depositing a carbon-rich material on the substrate to form a film, and after the depositing, activating the carbon-rich material to increase the surface area of the film of carbon-rich material. Due to the activation process being after deposition, this method enables use of low cost carbon-rich material to form a carbon electrode in the capacitor. The electrode may be used in capacitors, ultracapacitors and lithium ion batteries. The substrate may be part of the electrode, or it may be sacrificial—being consumed during the activation process. The carbon-rich material may include any of carbonized material, carbon aerogel and metal oxides, such as manganese and ruthenium oxide. The activation may include exposing the carbon-rich material to carbon dioxide at elevated temperature, in the range of 300 to 900 degrees centigrade.

Abstract: The invention provides a more economical carbon-fiber-reinforced carbon surfaced friction member, such as a brake disc, by replacing a disc which is of fiber-reinforced carbon throughout its thickness by a disc in which a fiber-reinforced surface layer is bonded to a base of a less expensive material, such as bulk graphite. A textile may be applied to the base and carbonized and carbon deposited on the textile layer by the multiple impregnation process or the chemical vapor deposition process. In the latter process the base is preferably heated above the temperature of the textile layer, e.g. by electrical induction or resistance, to obtain carbon deposition from the base outward through the textile layer.

Abstract: An improved process for drawing a continuous length of an acrylic multifilament fibrous material is provided. Prior to drawing at an elevated temperature by continuous passage through a suitable drawing zone the surface of the fibrous material is coated with powdered graphite (e.g. colloidal graphite) via contact with a dipersion containing the graphite paticles which serve to improve the drawing properties of the same. The process is suited for the hot drawing of a continuous length of an acrylic multifilament fibrous material (e.g. a substantially untwisted tow) which is intended for subsequent thermal stabilization, and cabonization to form a carbonaceous fibrous material.
