Superelastic shape recovery of mechanically twinned 3,5-difluorobenzoic acid crystals.

Satoshi Takamizawa1, Yuichi Takasaki.   

Abstract

Generally, superelastic behavior cannot be expected in mechanically twinned crystals because there is essentially no strain on the interface that is a driving force for spontaneous shape recovery. However, we found that single crystals of 3,5-difluorobenzoic acid are superelastic organic crystals under mechanical twinning. The unexpected shape recovery can be explained by molecular distortion on the twinning interface, which suggests a new mechanism for superelasticity in molecular materials.
