In flame retarded nanocomposites, a few percent of inert nanofiller, such as layered silicate (LS), can cause inorganic-carbonaceous protection layers to form during combustion [6-9], Other particles have also been proposed, including double-layered hydroxides, boehmite, and carbon nanotubes [10-14].
