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 curvature-dependent bending are subsequently carried… More >
