The present invention comprises the steps of (a) mixing the carbon nanotubes into a suitable dispersion solution; (b) sonicating the dispersion solution; (c) mixing the matrix material in the dispersion solution of step b; (d) sonicating the dispersion solution of step c; And (e) calcining the dispersion solution of step d. According to the above structure, the multi-walled carbon nanotubes are uniformly dispersed in the matrix to form chemical bonds at the molecular level, and the initial design volume fraction of the carbon nanotubes can be maintained in the final product, thereby ensuring reproducibility and reliability in manufacturing composite materials. can do. |
