Methods for forming a nanotube fabric with a controlled surface roughness (or smoothness) and a selected degree of rafting are disclosed by adjusting the concentration levels of a selected ionic species within a nanotube formulation used to form the nanotube fabric. In one aspect, the present disclosure provides a nanotube formulation roughness curve (and methods for generating such a curve) that can be used to select a utilizable range of ionic species concentration levels that will provide a nanotube fabric with a desired surface roughness (or smoothness) and degree of rafting. In some aspects of the present disclosure, such a nanotube formulation roughness curve can be used adjust nanotube formulation prior to a nanotube formulation deposition process to provide nanotube fabrics that are relatively smooth with a low degree of rafting.

Stem cell, bone and nerve scaffolding comprising discrete carbon nanotubes is disclosed. The discrete carbon nanotubes may be have targeted, or selective oxidation levels and/or content on the interior and exterior of the tube walls. The described scaffolding may be used to guide, target and protect stem cells upon injection into the body.

Discrete, individualized carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls are claimed. Such carbon nanotubes can have little to no inner tube surface oxidation, or differing amounts and/or types of oxidation between the tubes' inner and outer surfaces. These new discrete carbon nanotubes are useful in plasticizers, which can then be used as an additive in compounding and formulation of elastomeric, thermoplastic and thermoset composite for improvement of mechanical, electrical and thermal properties.
