Bundled carbon nanotubes are disentangled and dispersed using the principles of extreme pressure reduction of fluids carrying the bundled nanotubes. They are added to a high pressure fluid upstream of a chamber operated at much lower pressure. These high-low pressure ratios are preferably at least 100:1. As the high pressure fluid enters the lower pressure chamber it violently expands causing separation and disentanglement of the bundled carbon fibers. To further assist in this disentanglement a nozzle may be used at the inlet to the lower pressure chamber to direct the high pressure fluid against a hardened anvil in the chamber. This impact further aids disentanglement. Coating the nanotubes with a dispersant also improves disentanglement.
