Background: In the past years, there have been a great number of studies on the preparation, structure and properties of organic-inorganic polybenzoxazine nanocomposites. These studies aimed at improving the performance of the polybenzoxazine materials;
Objective: In this review, we summarize the recent progress in the studies on organic-inorganic polybenzoxazine nanocomposites, to give a clear clue of the studies on this topic. Method and Results: Preparation, characterization and correlation of morphologies with thermomechanical properties of organic-inorganic polybenzoxazine nanocomposites were addressed on the basis of the types of the nanoreinforcement agents such as layered silicates, polyhedral oligomeric silsesquioxanes (POSS) and other inorganic nano-fillers such as silica, carbon nanotubes and magnetite nanoparticles; Conclusion: Preparation of the organic-inorganic nanocomposites is an efficient way to improve the thermomechanical properties of polybenzoxazine thermosets.Keywords: Dielectric properties, functional properties, organic-inorganic nanocomposites, polybenzoxazine, thermodynamical properties.
