Abstract :
Poly (2-methoxy-5-octoxy-1, 4-phenylenevinylene) (MO-PPV) and functionalized multi-walled carbon tube (MO-PPV/MWNTs) composites with different MWNTs concentration were synthesized by in situ polymerization. The composites were characterized by AFM, PL spectra and UV-vis absorption spectra. The AFM phase image shows a good dispersion of MWNTs in the polymer matrix. PL and UV-vis spectra exhibited a blue shift of the main band.
