This article presents a comprehensive scientific evaluation of the structure–property relationships of
organosilicon materials using thermogravimetric analysis (TGA). Due to the high bond energy of the –Si–O– linkage,
polyorganosiloxanes and their derivatives exhibit remarkable thermal stability at elevated temperatures. By applying TGA
and DTG methods, the decomposition stages, onset and peak temperatures, residual mass, and decomposition rate of
the materials were accurately determined. Kinetic analyses based on the Kissinger and Flynn–Wall–Ozawa methods were
conducted to calculate the activation energy and assess the influence of structural parameters on thermal performance.
The results confirm that the thermal resistance of organosilicon materials directly depends on the chemical nature of side
groups, the degree of molecular branching, and the incorporation of nanofillers.
