Shape memory effect of chitosan/glycerol composite film in mixed water/ethanol solution

In this paper, a chitosan (CS)/glycerol (GL) composite film was prepared, and the solution‐responsive feature of the composite film in a mixed water/ethanol solution was investigated. The composite film began to show obvious shape recovery behavior when the water content of the mixed solution was more than 50% v/v. In mixed solutions, when the molar ratio of water molecules and ethanol molecules was more than 2:1, apart from the combination with...
