Carbon nanotubes or CNTs are carbon-based tubes whose size distribution is in the nm range. They are important as additives for lithium batteries, in nanofluids for solar energy systems. As an additive in fibre-reinforced plastics, for example for rotor blades in wind turbines, they play a decisive role in the extraordinary stability and resilience, with a relatively low weight. They are also of great importance for solid lubricants and self-lubricating surfaces. Nanocomposites containing CNT are used in hydrophobic and electrically conductive textile coatings as well as in membranes for the filtration of process wastewater. In order to optimize the energy density within lithium batteries, e.g., for electric cars, carbon onions with a multi-layer microstructure were developed. Graphene has also become indispensable in the world of electronics and photonics in the area of composite materials. The time-dependent determination of the sedimentation velocity of graphene nanoplatelets in aqueous surfactant solutions allows for new processes of liquid phase direct chemical exfoliation. LUM technologies allow you to determine the particle size distributions, the dispersibility in different media, also using the Hansen parameters, the quantification of the colloidal and separation stability. In the field of material testing, in particular for determining the adhesive strength of CNT-containing coatings and CNT composites, the LUMiFrac supports you reliably in a very flexible measuring range.
