    Immobilized carbon nanotubes on various surfaces
    (2015-08-04) Marti-arbona, Angel A.; Saha, Avishek; Pasquali, Matteo; Rice University; United States Patent and Trademark Office
    In some embodiments, the present invention provides methods of immobilizing carbon nanotubes on a surface, wherein the method comprises: (1) mixing carbon nanotubes with a superacid to form a carbon nanotube solution; and (2) exposing the carbon nanotube solution to the surface. The exposing results in the immobilization of the carbon nanotubes on the surface. In some embodiments, the method occurs without the utilization of carbon nanotube wrapping molecules. Other embodiments of the present invention pertain to systems that comprise immobilized carbon nanotubes on a surface, as developed by the aforementioned methods.

    Liquid crystals from single-walled carbon nanotube polyelectrolytes and their use for making various materials
    (2016-02-02) Marti-arbona, Angel A.; Jiang, Chengmin; Saha, Avishek; Pasquali, Matteo; Young, Colin; Rice University; United States Patent and Trademark Office
    In some embodiments, the present disclosure pertains to methods of forming a solution of single-walled carbon nanotube polyelectrolytes in a liquid crystalline phase. In some embodiments, such methods comprise: (a) providing single-walled carbon nanotube polyelectrolytes; and (b) mixing the single-walled polyelectrolytes with a polar aprotic solvent to form a mixture, where the mixing results in the formation of single-walled carbon nanotubes in the liquid crystalline phase. In some embodiments, the polar aprotic solvent comprises crown ether. In some embodiments, the present disclosure pertains to a method of making single-walled carbon nanotube fibers. Further embodiments of the present disclosure pertain to a method of making a single walled carbon nanotube composite. In some embodiments, the present disclosure pertains to an article comprising neat aligned carbon nanotubes.
