We report on peculiarly distinctive viscoelastic behaviors of the biobased water responsive polymer cellulose 10-undecenoyl ester, while biobased regenerated cellulose displays stronger hydroplastic behaviors. We discovered a novel hydrous deformation mechanism involving the stretching of hydrogen bonds mediated by hydroxyl groups and water molecules, serving as a crucial factor in accommodating deformations. In parallel, the microstructure of cellulose 10-undecenoyl ester with unique coexisting nanoparticles and a continuous phase of entangled chains is mechanically resilient in the anhydrous stateNano lettersViscoelastic Response in Hydrous Polymers: The Role of Hydrogen Bonds and Microstructure.PMC10979449INST186/1281-1/FUGGRef 3.5-1221348-CHN-HFST-PHuang CZhang KChen WBiehl PfalseViscoelastic Response in Hydrous Polymers: The Role of Hydrogen Bonds and Microstructure.Water responsive polymers represent a remarkable group of soft materials, acting as a laboratory for diverse water responsive physical phenomena and cutting-edge biology-electronics interfaces.
