    Abstract Kink defects in nanocellulose are ubiquitous yet associated questions remain open regarding the unclear microstructure-mechanical property relationship. Various kink patterns without molecular-scale resolution result in bemusements of how nanocellulose forms different kinks and what the fundamental mechanisms of reversible and irreversible kinks are. In our atomic force microscopy images of mechanically treated cellulose nanofibrils, bent nanofibrils usually exhibit small curvatures while kinked nanofibrils feature sharp bends, in which kinks are conspicuous due to their promiscuous configurations. To identify the nanomechanics of incipient kink defects formed in nanocellulose, molecular dynamics simulations of cellulose nanocrystals (CNCs) under… More >
