Carbon Nanotubes Dispersions dispersions are highly polished; however, they are difficult to disperse in the liquid. They are used as adhesives, coatings, and polymers. They are also used as conductive fillers to dissipate static charge in various electrical equipment. By adding nanotubes, polymers have increased resistance against chemicals, corrosiveness, increased temperature and pressure, and abrasion. CNT dispersion uses two approaches, the mechanical and chemical approaches. The mechanical approach is based on ultrasonication and high shear mixing. The chemical approach is based on covalent and non-covalent methods.
