Carbon nanotubes (CNTs) have been extensively studied because of their unique electrical, mechanical, thermal, and optical properties. Their ability to reinforce existing polymeric materials as well as to induce electrical conductivity into the polymer is very attractive. However, the nanotube aggregation, due to strong van der Waals interactions between the sidewalls, cause poor dispersion and stabilization of CNTs in many solvents. In this work, single-walled carbon nanotubes (SWNTs) are modified with a conjugated polymer with the aim of increasing the dispersion of CNTs without the loss of electronic properties. Poly(3-hexylthiophene) (P3HT) was chosen as a conjugated polymer to be attached on SWNTs because P3HT has outstanding electronic and optical properties, and good solubility in common organic solvents. The synthesis of P3HT-attached SWNTs (P3HT-SWNTs) and its characterization will be presented. |
