In this work, the preparation of poly (N-vinyl carbazole) (PVK) and carbon nanotubes (CNTs) or PVK/CNTs CPN nanocomposites film was carried out by an electrochemical approach. Solutions of the CNTs or multi-walled carbon nanotubes (MWNTs) with the PVK were prepared using mixed solvents aided by sonication which resulted in exfoliation and deaggregation of the MWNTs into the PVK polymer matrix. Cyclic voltammetry (CV) was carried out from spin-coated films of this homogeneous dispersion which resulted in the formation of a conjugated polymer network (CPN) nanocomposite film. The spectroscopic, electrochemical, and interfacial charge-transfer behaviour of the nanocomposites films were also analyzed using CV, UV-vis and fluorescence spectroscopy and spectroelectrochemical measurements. The use of polymers in making inverse opals is advantageous since they have unique mechanical, optical, and electrochemical properties. These properties are highly enhanced with the incorporation of CNT, which are known to have inherent electrochemical, electrical and mechanical properties.
