This book summarizes recent advances in epoxy vitrimer research, giving thorough discussion of the classification and fabrication of epoxy vitrimers and their composites. Epoxy vitrimers are reversible covalently crosslinked networks with dynamic covalent bonds, combining the excellent mechanical properties of thermosets with the re-processability of thermoplastics. The authors explore and summarize many current and potential applications of epoxy vitrimer composites across the domains of aerospace materials, electronic devices, machine manufacturing, and consumer products and technology. This book serves as an accessible introduction and a helpful guide to graduate students, researchers, and industry professionals in materials science and engineering with an interest in advanced polymer composites.
