Degradation Kinetics of Epoxy Nanocomposites in the Presence of Clay Nanoparticles: A Review

Abstract

The sudy of degradation kinetics of epoxy nanocomposites is very important because it can determine the temperature range and service life of the sysem. Degradation kinetics modeling has become widely used as an essential tool for engineers to predict the thermal durability of materials before their usage in indusry, leading to reduced coss and product development, manufacturing coss, time and quality of the designed product. Dispersion and disribution of clay nanoparticles in epoxy resin matrix are two important factors in the physical and mechanical properties of epoxy nanocomposites. Also, the inhibitory properties of clay nanoparticles or layered silicates agains hydrogen and oxygen, as well as the type of sructure can cause thermal sability of epoxy resin. Surface modifcation of the clay nanoparticles could play a delaying role in the degradation reaction of epoxy nanocomposites. The content of the added clay nanoparticles and the type of production process are two important factors in invesigating the degradation kinetics of epoxy resin in the presence of clay nanoparticles. In this paper, the efect of modifed and unmodifed clay nanoparticles on the degradation kinetics of epoxy resin and diferent models of degradation kinetics, activation energy, thermogravimetric analysis and weight loss percentage and the efect of diferent types of clay nanoparticles on the degradation kinetics of epoxy resin are reviewed.
