Free-radical chain polymerization of polymer nanocomposites

Free radical polymerization (FRP) is a diverse industrial process involving initiator decomposition, producing polymer networks including polymer nanocomposites. The FRP mechanism includes initiation, where an active center forms, propagation expands polymer chains through pi bond electrons, and termination influences chain length and initiator concentration. Nanocomposites synthesized via free radical chain polymerization significantly contribute to materials science, providing enhanced properties and versatile industrial applications. Despite its widespread use, challenges in controlling molecular weight distribution and microstructure limit precision for specific applications. Controlled chain polymerization, aided by computational quantum chemistry, aims to improve control, offering valuable contributions to modeling and enhancing nanocomposite polymerization with targeted properties. Computational quantum chemistry aids in understanding reaction mechanisms, predicting challenges, and designing accurate kinetic models for process optimization. This chapter critically evaluates considerations for choosing polymerization conditions, reaction mechanisms, predicting challenges, designing accurate kinetic models, and providing foundational knowledge for a profound understanding of nanocomposite polymerizations.
