Single-walled carbon nanotubes (SWNTs) have excellent electrical properties for a wide range of applications such as transistors, solar cells, photodetectors and chemical/biologic sensors. However, for all these applications, it is necessary to separate semiconducting SWNTs from metallic ones. Sorting SWNTs using conjugated polymers has been demonstrated to be a simple and low-cost method to effectively sort large quantities of semiconducting SWNTs.In this thesis, I first describe how semiconducting SWNT sorting can be improved by judiciously considering polymer design and solvent effects. A mechanism for the selective dispersion of semiconducting SWNTs is also proposed. As a result of improved semiconducting SWNT sorting, the application of SWNTs in printed transistors, solar cells and logic circuits is made possible. In particular, high-mobility, high on/off ratio transistors from the sorted semiconducting SWNTs are achieved. Then, I explain the development of n-type molecular doping and fluorinated dielectrics to control the threshold voltage of SWNT transistors as well as to improve the bias stability of the devices under ambient conditions. These advancements allow the fabrication of the first flexible SWNT complementary logic circuits with high reliability (high noise margin) and low power-consumptions. Finally, I discuss a novel technique to conform the shape of flexible SWNT electronics into 3-dimensional objects by utilizing shape memory polymers. The technique also allows conformal coating of the SWNT transistors and sensors to any irregular shaped-objects without degradation of device performance.
