Preview Abstract
Four different dispersants, sodium dodecyl benzene sulfonate (SDBS), cetyl trimethyl ammonium bromide (CTAB), polyvinylpyrrolidone (PVP) and polyacrylic acid (PA) were used to disperse carbon nanotubes(CNTs) composite plating solution. Dispersion effect was compared by the absorbance value of the bath. The analysis indicated that dispersants had variation of different dispersants on CNTs suspension, under the same technology condition, the dispersion effect of PA was better than PVP, CTAB and SDBS. When the optimum amount of PA was added, it had the good dispersion stability, the narrow particle size distribution and small average particle diameter. Surface quality of the slide bearings were significantly improved as well.
