In various embodiments a carbon nanotube molecular rebar formulation comprising a specific composition is disclosed. The composition comprises discrete carbon nanotubes that have at least a portion of the carbon nanotubes with a number average (ratio of number average contour length to end to end length) of greater than 1.1 and up to about 3. These discrete carbon nanotubes having the specified ratio of number average (tube contour length (TCL) to number average tube end-end length) ratio are not only discrete (separated) from one another, but are also controlled in their alignment such that processability and mechanical strength properties are both enhanced. Utility of the molecular rebar composition includes, but is not limited to improved composites, engineered materials, foams, sealants, coatings and adhesives, energy devices such as photovoltaics, batteries and capacitors, sensors and separation membranes. |
