Statistical Electron Microscopy, Rheometric Studies of Carbon Nanotube Solutions in Chlorosulfonic Acid and Characterization of Wire, Planar Antennas Manufactured from Macroscopic Carbon Nanotube Materials
… on the dispersion of CNTs in a true solvent: chlorosulfonic acid. This thesis focuses firstly on the development of statistical electron microscopy techniques to quantitatively estimate the length distribution of CNTs and qualitatively assess the alignment of CNTs in solution. Secondly, a …

Properties and processing of direct-spun carbon nanotube mats
… whilst immersed in organic solvents and in chlorosulfonic acid. Softening observed upon immersion in organic solvents is attributed to a reduced contact area between bundled nanotubes. Upon chlorosulfonic acid immersion nanotubes separate, resulting in ductile behaviour. A tensile drawing …

Chemistry of acenes, [60]fullerenes, cyclacenes and carbon nanotubes
… that are dissolved in concentrated sulfuric acid.</p><p>Cyclacenes may be useful precursors to synthesize SWNTs with uniform dimensions. We explored the supramolecular assembly of a bis[60]fullerene adduct of a 2,3,9,10-tetrasubstituted pentacene as a method to produce a [24]cyclacene …

Manipulation of Carbon Nanostructures for Multifunctional Composite Materials
… SWCNT fibers were impregnated with polyamic acid (PAA) solution at 100 psi followed by thermal imidization to obtain fibers reinforced with polyimide (PI). The tensile strength was increased form 68 to 215 MPa for SWCNT fibers after VPI and imidization. Surfactant-wrapped chemically converted …

Novel solution processing and characterization of aligned carbon nanotube materials for rapid composition-property relationship determination and additive manufacturing
… sub-milligram quantities of CNTs dissolved in chlorosulfonic acid (CSA) into films and fibers with high structural order. The aligned films have a high degree of order and exhibit anisotropic optical, electrical, and mechanical properties homogeneously over 10 cm2. We utilize this process to …
