Sonication Parameters Analysis of MWCNTs Monodispersion in Aqueous Solution of Triton X-100

Abstract:

Monodispersion of multi-walled carbon nanotubes with assistance of surfactants has become a usual procedure. A parametric analysis of sonication was performed in order to optimize the preparation procedure of MWCNTs monodispersion solution. MWCNTs solutions were characterized with results of UV-VIS absorbance and FT-IR spectra in order to find the optimal sonication time and power. Perfect sonication time obtained at the higher absorption peak 2.699 in 400nm is 42min, which can be define as sonication cycle. MWCNTs can achieve its optimum dispersion situation, when onication power is 270w, In this case, zeta potential can get as high as-45.2mv. Film achieved under combination of two kinds of optimization parameters is more smoothy and integrated.
