The radical trapping flame retardant mechanism of polymer-clay nanocomposites is frequently claimed to be responsible for improving the thermal stability of polymers. However it had so far never been demonstrated. Herein using in situ time-resolved X-ray Absorption Spectroscopy (XAS) we present experimental evidence that Fe3+ embedded in the clay can act as electron acceptors during polymer thermal decomposition. Therefore it contributes to improve the polymer thermal stability. Read more…
