Advanced chemical modification technology of inorganic oxide nanoparticles in epoxy resin and mechanical properties of epoxy resin nanocomposites: A review

Over the past several decades, the integration of IONs into EP emerged as an effective method for enhancing its mechanical properties. Nevertheless, challenges remain, especially with u-IONs, where the interfacial strength with EP is suboptimal, resulting in aggregation within the EP matrix and a subsequent deterioration in the mechanical performance of u-ION/EP nanocomposites. In this comprehensive review, we explored advanced chemical modification techniques tailored for IONs incorporated into EP, providing a detailed examination of the mechanical characteristics of surface cm-ION/EP nanocomposites. This review investigates various chemical modification methods and their distinct impacts on the mechanical attributes of the resulting EP nanocomposites. Special emphasis is given to addressing the persistent challenges of inadequate interfacial strength and aggregation. Furthermore, this article examines prospective surface modification approaches for inorganic oxide nanoparticles, offering a visionary outlook on methods to improve the mechanical performance of EP in future.
