Ossila M2438L2 is a grade of aligned multi-walled carbon nanotubes (MWCNTs, CAS 308068-56-6) supplied as a black powder with purity above 96%. The tubes run in a common direction parallel to the bundle axis, measure 8 – 18 nm in diameter and 25 – 95 μm in length, and are produced by chemical vapor deposition.
As a reinforcing filler, aligned MWCNTs give polymer composites greater stiffness than ordinary MWCNTs: an effective modulus of 13.2 GPa versus 6.4 GPa. They also improve electrical behaviour. Adding just 0.01 wt% to epoxy turns the otherwise dielectric resin into a conductor with a bulk conductivity of 10 -3 S/m.
Because the tubes are aligned, conductivity in the resulting composite is anisotropic, being nearly three orders of magnitude higher along the nanotube direction than across it. The material can be dispersed in DI water, DMF, THF, ethanol or acetone.
- Mechanical reinforcement of polymer composites to raise stiffness.
- Conductive filler for epoxy and other polymer composites.
- Fabrication of composites with direction-dependent (anisotropic) electrical conductivity.
- Research on carbon nanomaterials, 1D materials and thin film electronics.
