Solvent Processible Composite Carbon Nanotube Cathode for Polymer LED Applications
Keyword(s):
ABSTRACTComposites of single wall carbon nanotubes (SWNT) and conductive polymers were studied as potential cathode materials for application in polymer light emitting devices. A new conductive poly(2,7–9,9 (di(oxy-2,5,8-trioxadecane))fluorene) (PFO) possessing surfactant properties was used to stabilize SWNTs in solutions. The rigid PFO backbones act as a template while the ethyleneoxide side chains appear to wrap around the SWNTs. Up to 0.02% (by weight) of SWNTs are stabilized in the solution phase. The current vs. voltage behavior of the SWNT/PFO composite film (2% SWNT in PFO by weight) shows that most of the current is carried by SWNTs.
