Interfacial Interaction between Zn2+ and Surface Functional Groups Impacting Self-Assembly of ZnO on Cellulose Nanofibrils

The mechanism underlying the interfacial interaction between ZnO and surface functional groups, which drives the self-assembly of ZnO nanoflowers on the cellulose nanofibril (CNF) surface, remains inadequately understood. Moreover, the ideal sites for the loading and growth of ZnO nanoflowers on the oxygen atoms (O
