Using Agrawal integral equation to study the pyrolysis kinetics of exfoliated montmorillonite from a polyhedral oligomeric silsesquioxane surfactant and click chemistry

In this study, the exfoliated montmorillonite was prepared through the click chemistry of a propargyl-containing intercalator with singly or multiply azido-functionalized polyhedral oligomeric silsesquioxane nanoparticles. Thermogravimetric analyses revealed that the pyrolysis kinetics had a close relationship to the layered structures, exfoliated structures, and cage-like molecules of polyhedral oligomeric silsesquioxane nanoparticles. The pyrolysis of exfoliated montmorillonite had a mechanism function of Avrami–Erofeev equation, and the kinetic compensation effect equation revealed the pyrolysis.
