On the influence of nanotube properties, processing conditions and shear forces on the electrical conductivity of carbon nanotube epoxy composites
Nanotechnology, 2009Co-Authors: Josef Z. Kovacs, Roman E. Mandjarov, Thomas Blisnjuk, Martin Sussiek, Kirsten Prehn, Karl Schulte, Jörg Müller, Wolfgang BauhoferAbstract:We analyse statistical and kinetic percolation thresholds and maximum electrical conductivities of carbon nanotube epoxy composites as a function of shear forces, processing conditions, nanotube type and dimensions. Entangled and non-entangled nanotubes of different lengths (15-100 microm) and thicknesses (12-80 nm) have been obtained with three different synthesis methods based on catalytic or plasma enhanced chemical vapour deposition. The dispersions were processed either solely with a dissolver disk or additionally with a three Roll Calender. Care was taken to prevent unintentional shearing (e.g. through convection) in all samples that were not subject to deliberate shearing. It was found that shear forces have a similar influence on kinetic percolation thresholds and composite conductivities independent of nanotube types and dimensions.

EMEIT - Non-equant Roll Calender's structure design and analysis
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011Co-Authors: Ming XuAbstract:On the basis of equant Roll Calender, we have designed non-equant isometric Roll Calender which applied in macromolecule material. This kind of Calender can be realized by decreasing the diameter of one or two Rolls properly. And a pair of non-equant Roll Calender can be constructed by means of one big Roll and one small Roll. During the process of design, we have built the corresponding mathematical model. And we have calculated the non-equant Roll Calender's key problems in accordance with this mathematical model. By comparing with traditional Calender, non-equant Roll Calender has such advantages as high precision, low pressure load, low power consumption and rapid speed.
