Abstract

Composites of urea-formaldehyde/clay were synthesized and analyzed in the present study. The analyses of XRD, FTIR, DSC, and TGA were performed to investigate the variation of urea-formaldehyde (UF)/clay composites' structural and thermal properties with different clay loading levels. It was discovered that the clay loading level influences the glass transition temperature of UF resin. Thermo Gravimetric Analysis (TGA) has shown that the degree of clay loading and heating rate affects the composites' thermal stability. Furthermore, the curing reactions' activation energy was investigated using Kissinger's and Ozawa's methods, confirming the presence of interactions between the polymer chain and clay particles.
