This communication describes two methods for the synthesis of manganese sulfide/polyvinylcarbazole (MnS/PNVC) nanocomposites. The first method (method 1) involves initially the removal of the Hexadecylamine (HDA) molecules in the HDA-capped MnS nanoparticles, followed by the dispersion of the bare MnS (3 wt%) into PNVC. The FE-SEM and FT-IR established a strong interaction between the nanoparticles and the polymer while the absorption and photoluminescence spectra showed improved properties. The second method (method 2) is an in situ synthesis of MnS/PNVC composite. The method is similar to the single source precursor method but utilizes PNVC as the capping agent. The FE-SEM micrograph, EDX and FT-IR confirmed the formation of the composite. The optical properties confirm the role of PNVC to be that of a capping agent.
