Method & Evidence

AimTo investigate the self-assembly of cellulose nanocrystals induced by tannic acid for the creation of stable, self-healing hydrogels with tunable hierarchical porous structures.

MethodExperimental research involving chemical synthesis and material characterization.

ProcedureAqueous suspensions of cellulose nanocrystals (CNCs) were mixed with tannic acid (TA) to induce gelation. The resulting hydrogels (SH-CNC/TA) were characterized for their porous structure, mechanical properties, and self-healing capabilities. FTIR spectroscopy and atoms in molecules topology analysis were used to understand the bonding mechanisms. The effect of varying the CNC to TA mass ratio on the hydrogel properties was investigated. Further structural enhancement was explored by introducing metal cations.
