Nanocomposite polymers, fire ignition time

A disappointment in the observations of the flame-retardant behavior of clay in polymers was the decrease in the time to ignition for polymer-clay nanocomposites when compared to pure polymer. The commercial quaternary ammonium ions that were utilized to modify the surface of the clay for improved exfoliation efficiency in the polymers studied are prepared from fats and oils. The presence of these quats in the polymer-clay nanocomposites is tantamount to throwing fat into the fire. The decrease in the time to ignition for the polymer-clay nanocomposites that contain quats prepared from fats and oils is expected. Removal of some of the surfactant from the clay by extraction resulted in a longer time to ignition time for the polymer-clay nanocomposite prepared with the clay with lower surfactant content [48]. [Pg.166]
