Exploring of the property of epoxy resins based on diselenide and disulfide dynamic linkers

Frontiers in Chemistry, 2022
Over the last decade, there has been a lot of interest in incorporating dynamic covalent bonds (DCBs) into epoxy resins. Because diselenide and disulfide bonds have similar properties, they are frequently used as DCBs in self-healing epoxy networks.
