To what extend is the thermal degradation kinetics data relevant to design the pyrolytic system for a polymer composite? Can the modification of a raw polymer into composite give the study more significance?
Thermal degradation kinetics provide a quantitative understanding of electrical degradation under various stress biases and ambient temperatures. The kinetics of thermal degradation is usually studied by thermogravimetric analysis (TGA), which is based on measuring the mass loss rate of a microscale sample and the temperature of the surrounding fluid during controlled heating. Using dimensional analysis to derived two upper bound thresholds for the initial mass as a function of heating rate above these thresholds heat transfer effects are significant. One threshold is calculated based on interparticle heat transfer and depends on flow conditions, material and fluid properties. The intraparticle heat transfer depends on material properties leads to a better understanding of the pyrolysis chemistry of polymers.
