Research Abstract

Although single-walled carbon nanotubes (SWNTs) have extraordinary optical, electrical, thermal, and mechanical properties, the lack of their solubility in any solvents results in a marked impediment toward harnessing their applications. In this study, dispersibility of SWNTs has been improved by covalent and noncovalent methods to fabricate composite materials with conjugated polymers, porphyrins, and fullerenes. Optical and photoelectrochemical properties of the composites were investigated in detail.
