Cellulose triacetate (CTA) was doped with poly(N-vinylcarbazole) (PVK) via the oxidative polymerization of N-vinylcarbazole with ferric chloride to form polymer blends. Langmuir-Schaefer (LS) films of the polymer blends were fabricated. The morphology of the cellulose triacetate-poly(N-vinylcarbazole) (PC) blends were analyzed using transmission electron microscopy. The pressure-area isotherm of PC blends revealed the possibility of compact monolayer formation at air-water interface. The voltammetric investigation of PC blends showed an appreciable electrochemical behavior. The photoinduced charge transfer across a donor/acceptor hybrid interface provided an effective method to study the photoelectrochemical properties of the PC polymer films. (C) 2010 Elsevier B.V.
