Irregular and suppressed elastic deformation by a structural twist in cellulose nanofibre models

Abstract The elastic responsiveness of single cellulose nanofibres is important for advanced analysis of biological tissues and their use in sophisticated functional materials. However, the mechanical responsiveness derived from the twisted structure of cellulose nanofibres (CNFs) has remained unexp...
