AbstractA detailed study of poly(alkylthiophene) self-assembly and organization on single-walled carbon nanotubes is presented. We show that ordered polymer domains are formed when a conjugated polymer is blended with small amounts of carbon nanotubes. By correlating the lowest energy feature in the absorption spectra of the polymer with ordering, we demonstrate that the degree of ordering in the polymer is enhanced when it is blended with carbon nanotubes. Furthermore, we elucidated the conformation of the polymer chain when it is absorbed onto the nanotube surface and imaged the high degree of ordering in the polymer/carbon nanotube complex by microscopy.

We report on the optical properties of fabricated nanohybrid structures containing Au nanorods and functionalized single-walled carbon nanotubes in aqueous solutions. In particular, the absorption spectra of these hybrid materials are studied as a function of the concentration of the functionalized single-walled carbon nanotubes as well as the evolution time following preparation. The absorption spectra show a red shift of the longitudinal plasmon mode of the Au nanorods along with the emergence of broadened structures at wavelengths between 1000 and 1100 nm. These results, supported by TEM images, indicate the self-assembly of the Au nanorods forming on the sidewalls of the functionalized SWNTs driven by polyelectrolyte interactions.
