Carbon nanotubes (CNTs) are hollow cylindrical tubes with nanometer scale diameters and lengths up to a few
conferring to the polymer a different dispersing power [93].
Another example of reversibledispersion/precipitation of CNTs is the folic acid (FA)/SWCNT system. The insolubility of folic acid in acidic aqueous solutions prevents it acting as a CNT dispersant. Nevertheless, once CNTs have been FA-coated, the
