Polypropylene (PP) polymer nanocomposites reinforced with a variety of nanofillers including magnetic nanoparticles, carbon nanotubes, magnesium hydroxide, aluminum hydroxide, and synergist silicon dioxide were prepared through in- or ex- situ solution mixing method for reducing the flammability and enhanced flame retardancy. In order to improve the filler dispersion quality and reduce the polymer-filler interfacial tension, the nanofiller surface pre-treatment/functionalization and the aid of surfactant were used during the preparation of these different PP nanocomposites. The physicochemical properties of thus prepared nanocomposites including thermal stability, flammability, melting rheological behaviors were studied using thermogravimetric analysis, micro-scale combustion calorimetry and rheometry. The thermal stability and flame retardation mechanism for each composition will be discussed in detail and the advantages as well as the disadvantages for lowering the flammability will also be compared.
