Epoxy resin is one of the three thermosetting polymer materials. Due to its excellent comprehensive properties, it is widely used in many fields such as coatings, adhesives and electrical applications. Bio-based epoxy resin prepared from renewable biomass raw materials can alleviate fossil energy crisis and reduce environmental pollution, which satisfies the needs of sustainable social development. In this paper, the recent research progress on bio-based epoxy resin in high performance and functionalization was summarized. Especially, it is focused on the main problems restricting the application of epoxy resin, such as low heat resistance, poor flame retardancy and toughness. The performance advantages of bio-based epoxy resin were introduced, combining with the research of the author’s group and other researchers worldwide. This paper would provide a reference for the future development of bio-based epoxy resin.
