Metallic SWCNTs electrically conductive composite

Carbon nanotubes are synthesized using metal catalysts, which are later difficult to remove fiom the nanotubes to assure high purity. These impurities develop pseudocapacitive properties of CNT-based actuators. The trend in carbon-based actuators is to find alternatives to CNTs, especially to SWCNTs, mostly because of their high cost. CNTs have still unique properties and by far better electrical conductivity compared to amorphous carbons, and rather than replacing, the combination of CNTs with different types of amorphous carbons in electroactive carbon-polymer composite actuators is the prospect.
