چکیده انگلیسی
Rheological results were used to determine the optimum type of dispersant and its concentration for six commercial dispersants for the dispersion of multi-walled carbon nanotube (MWCNT) agglomerates in texanol. An unsaturated polycarboxylic acid copolymer (BYK P-104) exhibited the optimum performance with the lowest MWCNT slurry viscosity in texanol. The cutting and dispersion efficiencies of MWCNTs with 20Â wt.% of BYK P-104 dispersant were compared using conventional ball milling and high energy milling, whereby the latter was found to be more effective. High energy milling for 2Â h produced a large portion of MWCNT agglomerates smaller than 150Â nm, showing a drastic increase in slurry viscosity due to the dispersion into individual CNTs. On the other hand, 120Â h ball milling was required to achieve the agglomerate size of 300Â nm with less viscosity increase upon milling. Decrease in the degree of MWCNT crystallinity was observed by both milling, even though 2Â h high energy milling showed slightly less damage than 120Â h ball milling based on XRD and Raman spectroscopy results.
