Functional Conjugated Polymers for Noncovalent Engineering of Carbon Nanotubes and Sensing Applications Haiying Liu Department of Chemistry, Michigan Technological University, MI 49931 Rigid functional conjugated poly(arylene-ethynylene)s have been successfully used to solubilize carbon nanotubes in different solvents including water. This unique approach represents the first example of carbon nanotube solubilization via - stacking without polymer wrapping and enables superior control of the relative placement of functionalities on the nanotube surface while still preserving nearly all of the nanotube’s intrinsic properties. Homogeneous carbon nanotube/polymer composites were fabricated using noncovalently functionalized, soluble single-walled carbon nanotubes (SWNTs). These composites showed dramatic improvements in the electrical conductivity with very low percolation threshold ~ 0.05–0.1 wt % of SWNT loading. By significantly improving the dispersion of SWNTs in commercial polymers, we showed that only very low SWNT loading is needed to achieve the conductivity levels required for various electrical applications without compromising the host polymer’s other preferred physical properties and processability. In contrast to previous techniques, our method is applicable to various host polymers and does not require lengthy sonication. This is one of a very few nanotechnologies which are making a big profit since its patent (USA Patent 6905667) has been licensed to Zyvex Corporation for commercialization of carbon nanotube composites for a variety of applications including sporting goods equipment.
