In this work, the efficiency of in situ polymerization for the production of polyvinylcarbazole nanocomposites with reduced graphite oxide‐zinc oxide hybrid nanoparticles is evaluated. The ZnO nanoparticles are previously synthesized by the sol‐gel method. The cationic polymerization of polyvinylcarbazole is successfully performed in the presence of the nanoparticles using boron trifluoride as initiator and dichloromethane as solvent at 0 °C. The incorporation of the nanoparticles into the polymer can be observed by X‐ray diffraction (XRD) analysis, where the characteristic peaks of the structures are observed. In addition, the XRD indicates a hexagonal wurtzite structure of the ZnO nanoparticles. Polymerization shows a yield of almost 100%, with a short reaction time and total conversion of the monomer to high molar mass polyvinylcarbazole, having very high stability to thermal degradation.
