Advances in Plant Oil-Based Polymeric Materials with Dynamic Covalent Bonds

Abstract

With the current unstable supply of petroleum resources, the environmental pollution problems, as well as the increasing demand for sustainable development, natural renewable resource plant oil has been regarded as a potential alternative resource of petrochemical-based materials to fabricate polymers, due to the advantages such as renewability and wide availability. However, traditional plant oil-based polymer materials have limitations in terms of recyclability and reprocessability. In recent years, dynamic covalent bond polymers have undergone rapid development, which hold significant promise for addressing the inherent trade-off between performance and sustainability in traditional polymeric materials, thereby offering innovative solutions for sustainable development. This review summarizes the fundamental characteristics of plant oil resources, along with the evolution and characteristics of dynamic covalent bonds, and the two primary exchange mechanisms of covalent adaptable networks (CANs), and recent advances in plant oil-based dynamic covalent polymer materials were reviewed. The review discusses the utilization of various dynamic covalent bonds in polymer material design, while providing perspectives on future developments in this field.
