Thermal stability and degradation kinetics of novel organic/inorganic epoxy hybrid containing nitrogen/silicon/phosphorus by sol-gel method

Two methods have been used to study the degradation of hybrids containing silicon, phosphorous and nitrogen hybrid during thermal analysis. These investigated methods are Kissenger, Ozawa's methods. The activation energies (Ea) were obtained from these methods and compared. It is found that the values of Ea for modified epoxy hybrids are higher than that of pure epoxy. The hybrids of high activation energy possess high thermal stability.
