Abstract:
1. A method of manufacturing a carbon nanotube reinforced composite material comprising hydrophilic carbon nanotubes and a synthetic resin, comprising the steps of: dispersing the hydrophilic carbon nanotubes in a first solvent to prepare a first dispersion liquid, adding the first dispersion liquid and a synthetic resin raw material to a second solvent and stirring the resulting mixture to prepare a third dispersion liquid where a second dispersion liquid in which the synthetic resin raw material is dissolved in the first dispersion liquid is dispersed in the second solvent, removing the first solvent and the second solvent from the third dispersion liquid to obtain a mixture of the hydrophilic carbon nanotubes and the synthetic resin raw material, and molding the mixture to obtain the composite material where the synthetic resin is reinforced with the hydrophilic carbon nanotubes, wherein the second solvent has smaller solubility of the synthetic resin raw material than that of the first solvent, is substantially not compatible to the first solvent, and has volume larger than that of the first solvent.
