Synthesis of hybrid materials based on poly(3-hexylthiophen) and modified multiwalled carbon nanotubes

Abstract

In this study, we reported a new method to synthesize hybrid materials from P3HT and modified MWNTs through S_N² mechanism using a catalytic system of tetrabutylammonium fluoride in THF (TBAF/THF). Experimental results obtained by scanning electron microscope (SEM), transmission electron microscope (TEM), Raman spectra and sedimentation test confirmed the core-shell structure of the grafted P3HT/MWCNTs. The hybrid material was higher soluble in organic solvents (stable for more than 6 weeks) as well as better thermal stability than P3HT/MWNTs composite.
