Résumé : |
Carbon nanotubes can be used to reinforce composite materials and provide electrical conductivity. Typical carbon nanotube loadings range from 0.2 to 1 wt%, which makes them a highly competitive additive. Since their direct incorporation in the host matrix, i.e. from raw powder, requires extensive know-how, Arkema has developed ready-to-use solutions consisting in highly-loaded concentrates. Compared with liquid dispersions offered on the marketplace which typically contain less that 2 wt% of carbon nanotubes, these concentrates offer enhanced formulation flexibility and ease of use, while reducing costs. |
