3. Nanocomposites and fire behavior

A nanocomposite material is a two-phase material with a dispersed nanoscale particulate phase (nanoparticles). The matrix phase can be polymeric, metallic or ceramic . In this dossier, only polymer-matrix nanocomposites will be considered. The development of polymer-matrix nanocomposites since the 1990s has been driven by the considerable impact of nanostructuring on the functional properties of these materials, particularly mechanical properties (reinforcement) and barrier properties (gas and solvent permeability) in the case of nanocomposites containing lamellar nanoparticles
