The improvement in physical properties of metal matrix composites using CNTs has been studied. Generally, the dispersant for CNTs is necessary to distribute CNTs into the metal matrix uniformly. However, dispersant-free process is desirable because dispersant makes especially electrical properties of composites worse. Therefore, we studied dispersant-free CNT dispersion process focusing on functional groups on the surface of CNTs.
