ABSTRACT
This chapter investigates the influence of different multi-walled carbon nanotubes (MWNTs) on the physical and chemical properties of poly(o-ethoxyaniline) (POEA) nanostructured films. The nanocomposites were synthesized by in situ chemical oxidative polymerization under identical conditions, and thin solid films were prepared by using the Langmuir-Schaefer (LS) technique. Different properties were measured and compared with POEA to find out whether the introduction of different MWNTs concentrations could affect the properties of POEA-MWNT composite materials. It was found that the presence of MWNTs in POEA enhances the interaction between the aromatic structure of the POEA and the basal plane of the MWNT graphitic surface via p-stacking,
affecting the vibrational modes of the polymer. Furthermore, an improvement in the thermal stability and surface morphology was also observed.
