Carbon nanotubes have been studied extensively because of their exceptional mechanical, thermal, and electrical properties that can be utilized for many applications. Current synthesis methods create a mix of both metallic and semiconducting nanotubes. For most applications, segregation and alignment of these nanotubes is desired. One promising method is to wrap the nanotubes with polymers. However, polymer-nanotube composites are complex and not well understood. This project seeks to understand the relevant interactions using a variety of methods including rheological techniques to find possible applications of these composites. Current focus has been with poly (3-hexyl thiophene)-single-walled carbon nanotube composites. Depending on the solvent, concentration, and temperature, these composites have been shown to have liquid crystalline and gel-like properties. A major part of this project will be optimizing and manipulating these properties to discover new applications.
