The objective of this research effort was to develop and explore chemical processing and analysis techniques for enabling self-assembly of CNTs into controlled architectures. Work focused both on 1 developing chemistries useful for enabling the synthesis of CNT-based objects suitable to enabling self-assembly and on exploring conditions for driving the self-assembly process. A new technique was developed for assaying the surface functional chemistry of chemically treated CNTs was developed to enable high precision quantitative analysis of linkage sites on the CNT surface. Various sidewall functionalization techniques were explored for tailoring the CNT properties. Anomalous behavior was observed for the solubilization properties of amine containing functional groups these observations will require further exploration to understand the origin and technological implications of these effects. Self-assembly of the targeted nano-architecture was not observed under the conditions explored in this study and provides insights into probable constraints governing this type of self-assembly.
