Dispersion of Single-Walled Carbon Nanotubes in Organic Solvents DMAC

The effective use of single walled carbon nanotubes (SWCNT) for improving mechanical properties of polymers is the key to the efficient diffusion of carbon nanotubes into organic solvents to form a stable single solution. The single walled carbon nanotubes in dimethylacetamide (DMAc) with different dispersion methods (including homogenizer, ball mill, micro jet machine) were studied in this paper, adding different organic compounds (dispersant, polyacrylonitrile) and different chemical treatment methods (acid purification, etc.) affect the dispersion of single wall carbon nanotubes were also discussed. The best dispersing time, the effects of different conditions on the basic properties of Single-walled carbons and on the dispersed state of carbon nanotubes were determined by using optical microscopy, scanning electron microscopy, Raman and elemental analysis, in order to get the optimal dispersion conditions of single-walled carbon nanotubes in DMAc.
