Kinetics of Fluorescein Sodium Salt /Polystyrene (FFS/PS) Composites by TG Technique

The fluorescein sodium salt (FSS) /polystyrene (PS) composites were prepared by powder metallurgy method (PM). The thermal behavior of the composites was characterized by thermogravimetric analysis (TG) technique. It is observed that the composites decompose in two steps. The kinetic parameters (activation energy, frequency factor) and thermodynamic parameters (enthalpy DH# change, entropy change DS# and Gibbs free energy change DG# were calculated from the TG curves. Eight g(a) functions for decomposition mechanism (DM) were used to evaluate the kinetic parameters and analysis of experimental results suggests that in the first decomposition step, the actual DM is D3 type which is the three-dimensional diffusion mechanism for the first decomposition step of the composites. But, in the second decomposition step, it was observed that the decomposition mechanism is from one-dimensional diffusion (D1) to the random nucleation mechanism (F1).
