Dispersions of carbon nanotubes in copolymer solutions and functional composite materials and coatings therefrom |
摘要 |
A dispersion includes non-chemically modified carbon nanotubes, a soluble block copolymer providing at least one block of a conjugated polymer and at least one block of a non-conjugated polymer, and at least one solvent. At 25° C. exclusive of any mechanical force and after one hour, at least 90% of the carbon nanotubes exist in the dispersion as isolated carbon nanotubes. The components of the dispersion can be combined with a polymer miscible with the block copolymer to form a carbon nanotube polymer composite upon removal of the solvent. The dispersion can be cast on a substrate and then dried to form a coating, including forming a superhydrophobic coating on the substrate. The non-conjugated polymer of the block copolymer or another miscible conjugated polymer including a copolymer can include functionalities that non-covalently attach to the carbon nanotube surface, such as for enhanced solubility or enhanced biocompatibility.
