Influence of the sonication temperature on the debundling kinetics of carbon nanotubes in Propan-2-ol
journal contribution
posted on 2013-01-01, 00:00 authored by Ludovic Dumee, K Sears, J Schütz, N Finn, M Duke, S GrayThe effect of sonication temperature on the debundling of carbon nanotube (CNT) macro-bundles is reported and demonstrated by analysis with different particle sizing methods. The change of bundle size over time and after several comparatively gentle sonication cycles of suspensions at various temperatures is reported. A novel technique is presented that produces a more homogeneous nanotube dispersion by lowering the temperature during sonication. We produce evidence that temperature influences the suspension stability, and that low temperatures are preferable to obtain better dispersion without increasing damage to the CNT walls.
