- Description:
- Carbon nanotubes (CNTs) have exceptional properties and are mass-producible at the ton scale as aggregated powders, but their difficulty in processing is a significant barrier to widespread use. Even after decades of research, there still isn’t a solvent for CNTs that is massively available, easily removable, and non-damaging. The need...
