Flame retardancy and charring behavior of polystyrene‐organic montmorillonite nanocomposites

Abstract: The fire performance of polystyrene‐organic montmorillonite (OMMT) nanocomposite was investigated by limiting oxygen index (LOI) and cone calorimetry. Scanning electron microscopy, electron dispersive spectroscopy and attenuated total reflection Fourier transform infrared spectroscopy were employed to study the charring process of the nanocomposite. The residue collected upon thermal degradation was analyzed by various means to determine its composition and to understand the flame‐retardant mechanism of the na… Show more

“…So, end users pursue less controversial alternatives including nonhalogenated phosphorous [3,4] mineral fillers (metal hydroxides, layered double hydroxides, clays) [5][6][7][8][9][10][11] , inorganic nanofillers [12,13] , and boratebased [14] or organic silane [15] flame-retardant formulations.…”

“…In recent years, halogen-free flame retardation of polymers has gained increasing attention because the application of traditional halogenated compounds is restricted for environmental reasons. [1][2][3][4][5] Extensive work has been performed to endow polymer materials with good flame retardancy and smoke suppression. At present, a large variety of nontoxic materials have been studied, such as aluminum trihydrate (ATH), magnesium hydroxide (MH), and phosphorus-containing compounds, which are replacing halogen compounds as flame retardant and smoke suppressant fillers for thermoplastics.…”

“…When organoclay is added to the DOPO/epoxy blend, the amount of the residual char gradually increases with an increase in the loading of organoclay, and the residual char becomes thicker, the char on the surface of the composite turns more compact and continuous, especially when the organoclay loading reaches 6 wt %. This demonstrates that the thermal stability of the organoclay nanocomposite has increased remarkably than neat EP and DOPO modified epoxy systems …”
