Abstract: A composite member and a method for manufacturing polymeric material article are presented. The method comprising providing polymeric resin, providing selected amount of filler material, mixing filler material into the polymeric matrix to provide a polymeric filler mixture, compressing said polymeric filler mixture under pressure in the range of up to 350 bar, and curing said polymeric filler mixture to provide stable polymeric material. The resulting composite member is typically characterizes by having average filler to filler particle gap below 20 nm and substantially does not have air voids therein.

Abstract: Carbon nanotube reinforced polymers include a polymer and carbon nanotubes reinforcing the polymer. The carbon nanotube reinforced polymer exhibits a conductivity percolation threshold of less than 106 ?/cm at a carbon nanotube content of 1.5 wt. % and less. The polymer may be selected from a polyamide or a polystyrene based polymer. In certain embodiments, the carbon nanotube content is between 0.1 to 1.5 wt. %, and the reinforced polymer will have a percolation threshold at a carbon nanotube content of less than 0.5 wt. %.

Abstract: The present invention relates to a process for the preparation of a carbon nanotubes reinforced polymer. The process comprises the following steps: a) contacting carbon nanotubes in an aqueous medium with a water-soluble component, comprising either a water-soluble first polymer or a water-soluble surfactant; b) mixing the resulting product from step A) with either an aqueous latex of a second polymer, or with (a) water-soluble precursor(s) of a second polymer; c) removing water from the so obtained mixture; d) heating the product from step C) to a temperature at which the second polymer flows or where the second polymer is formed from out of its precursor(s); and e) processing and/or solidifying the product of step D) into a desired form. As a result the carbon nanotubes retain essentially their original aspect ratio. As a result, mechanical and conductivity properties are improved.

Abstract: A method is provided for exfoliation of carbon nanotubes and for the preparation of a stable aqueous suspension thereof containing dispersed, essentially single tubes, using a water-soluble polymeric material. A powder of carbon nanotubes is further provided, that can be re-dispersed to form a stable suspension. The nanotubes can be used in electronics, printing, coatings, thin layers, molecular machines, and for the production of composite materials.
