<p>Producing a composite material comprises (a) providing a dispersion comprising functionalized carbon nanotubes in a first epoxy resin, (b) adding a curing agent to the dispersion of the step (a), (c) introducing the dispersion of the step (b) into a mold, and (d) curing the dispersion of step (b). Producing a composite material comprises (a) providing a dispersion comprising functionalized carbon nanotubes in a first epoxy resin, (b) adding a curing agent to the dispersion of the step (a), (c) introducing the dispersion of the step (b) into a mold, and (d) curing the dispersion of step (b), where: the first epoxy resin comprises a bisphenol A epoxy resin; the functionalized carbon nanotubes are obtained by reacting carboxyl group-containing carbon nanotubes with a second, bisphenol A epoxy resin comprising epoxy resin; the carboxyl group comprising carbon nanotubes are obtained by reacting carbon nanotubes with a reaction mixture comprising nitric acid; the first and the second epoxy resins are same or different; and the amount of functionalized carbon nanotubes in the dispersion of step (a) is 1-10 wt.%, relative to the total weight of the dispersion. An independent claim is included for use of the dispersion of functionalized carbon nanotubes in the first epoxy resin to produce the composite material.</p> |
