Morphology and photoconductivity of poly-N-vinylcarbazole-cellulose triacetate Langmuir–Schaefer films

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.
