181 Carbon fibrils, method for producing same and compositions containing same US678701 1984-12-06 US4663230A 1987-05-05 Howard G. Tennent
This invention concerns an essentially cylindrical discrete carbon fibril characterized by a substantially constant diameter between about 3.5 and about 70 nanometers, e.g. between about 7 and 25 nanometers, length greater than about 10.sup.2 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region, each of the layers and core disposed substantially concentrically about the cylindrical axis of the fibril. Preferably the entire fibril is substantially free of thermal carbon overcoat. The invention further concerns a plurality of such fibrils.The fibril or plurality of fibrils of this invention may be produced by contacting for an appropriate period of time and at suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850.degree. C. and 1200.degree. C., the ratio on a dry weight basis of carbon-containing compound to metal containing particle being at least about 100:1.The fibrils are useful in composites having a matrix of e.g., an organic polymer, an inorganic polymer or a metal. In one embodiment the fibrils are incorporated into structural materials in a method of reinforcement. In other embodiments the fibrils may be used to enhance the electrical or thermal conductivity of a material, to increase the surface area of an electrode or capacitor plate, to provide a support for a catalyst, or to shield an object from electromagnetic radiation.

184 Treatment of carbon or graphite fibers and yarns for use in fiber reinforced composites US3671411D 1970-03-03 US3671411A 1972-06-20 RAY JAMES D; STEINGISER SAMUEL; CASS ROBERT A
Carbon fiber or yarn as used in fiber reinforced composites is electrolytically treated to improve the surface characteristics and thereby to improve its bonding or adhesion to the matrix material. By this improved bonding, shear strengths of resultant fiber resin or plastic composites have been more than doubled. The electrolytic treatment is conducted by using the fiber or yarn as the anode and using en electrolyte such as an aqueous caustic solution.

189 METHOD FOR ELECTROCHEMICALLY PRODUCING CARBON MATERIAL WITH ITS SURFACE MODIFIED BY FUNCTIONALISED GROUPS, NOVEL CARBON MATERIAL WITH MODIFIED SURFACE AND ITS APPLICATION PCT/FR1998/000437 1998-03-05 WO98040540A1 1998-09-17

190 MOLECULAR SELF-ASSEMBLY OF ELECTRICALLY CONDUCTIVE POLYMERS PCT/US9407182 1994-06-24 WO9502251A3 1995-03-02 RUBNER MICHAEL F; CHEUNG JOSEPHINE HO-WAH
A molecular self-assembly process based on the alternating deposition of a p-type doped electrically conductive polycationic polymer and a conjugated or nonconjugated polyanion or water soluble, non-ionic polymer has been developed. In this process, monolayers of electrically conductive polymers are spontaneously adsorbed onto a substrate from dilute solutions and subsequently built-up into multilayer thin films by alternating deposition with a soluble polyanion or water soluble, non-ionic polymer. In contrast to a deposition process involving the alternate self-assembly of polycations and polyanions, this process is driven by non-covalent bonded attractions (for example, ionic and hydrogen bonds) developed between a p-type doped conducting polymer and a polymer capable of forming strong secondary bonds. The net positive charge of the conducting polymer can be systematically adjusted by simply varying its doping level. Thus, with suitable choice of doping agent, doping level and solvent, it is possible to manipulate a wide variety of conducting polymers into exceptionally uniform multilayer thin films with layer thicknesses ranging from a single monolayer to multiple layers.

Волокно в частном случае помещают в рабочую камеру с расположенной внутри нее газовой средой, нагрев газовой среды осуществляют путем нагрева камеры (например, ее стенок) одновременно с обработкой волокна микроволновым излучением. Согласно второму аспекту изобретения заявлен способ получения углеродного волокна, который включает в себя по крайней мере этапы стабилизации и карбонизации волокна, в котором стабилизацию предшественника осуществляют вышеописанным способом путем воздействия на волокно микроволновым излучением с одновременным нагревом среды, в которой помещено волокно. После карбонизации волокна, как вариант, возможно его дополнительная графитация.

В результате снижается время стабилизации волокон предшественников, что влечет за собой снижение энергозатрат и повышение производительности процесса получения углеродного волокна.
