Cyclodextrin (CD) is a cyclic oligosaccharide made from starch, and its ability to selectively incorporate molecules into its ring has led to various applications. Initially, it is used for the stabilization and solubilization of drugs in water, and it has since been used in food and additives [1]. Today, it is used in everyday items such as deodorants. Recently, as CD has become cheap and readily available, it has been studied for use in structural materials such as polymers. Currently, the development of new materials (supramolecular materials) based on the interaction between CD and guest molecules is progressing [2]. Supramolecular materials containing polyrotaxanes with many CDs embedded in polymer chains and gels and elastomers cross-linked by host-guest interactions between polymer side chains have been developed and are being deployed in various applications [3, 4].
