Publication number: 20100072432Abstract: 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. %.Type: ApplicationFiled: May 6, 2009Publication date: March 25, 2010Applicants: STICHTING DUTCH POLYMER INSTITUTE, BEN-GURION UNIVERSITY OF THE NEGEV RESEARCH AND DEVELOPMENT AUTHORITYInventors: Cornelis E.

Patent number: 7569637Abstract: 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.Type: GrantFiled: February 12, 2004Date of Patent: August 4, 2009Assignees: Stichting Dutch Polymer Institute, Ben-Gurion University of the Negev Research and Development AuthorityInventors: Cornelis E.
