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.
