Carbon nanotubes facing competition from new nanomaterials.
Once the most promising of all nanomaterials, carbon nanotubes (CNTs) face stiff competition in conductive applications from graphene and other 2D materials and in composites from nanocellulose. However, after considerable research efforts, real CNT products are coming to the market. Transparent conductors (TCs), battery additives and transistors represent the most promising markets for CNTs. CNTs are widely viewed as viable candidates as alternatives to indium tin oxide (ITO) in TCs and SWNTs are a leading candidate to replace silicon in transistors.
