Effect of nanosized carbon black on thermal stability and flame retardancy of polypropylene/carbon nanotubes nanocomposites
In recent years, there is a high level of interest in using nanoscale fillers for preparing polymer nanocomposites with improved thermal properties and flame retardancy. Typically, an obvious reduction in the heat release rate (HRR) was observed in polypropylene/carbon nanotubes (PP/CNTs) nanocomposites with only lwt％ of CNT content21. The most dominant mechanism was attributed to the insitu formation of a continuous, network structured protective layer from the tubes, which acted as a thermal shield for energy feedback from the flame. Clay, C60, POSS and other nanofillers were also extensively employed to prepare polymer nanocomposites, in which all of them exhibited some favorable effect on improving thermal stability and flame retardant of polymer matrix. Very interestingly, the combination of different nanoparticles could present a synergistic effect on improving the flame retardancy of polymers.
