Cellulose nanocrystal/collagen hydrogels reinforced by anisotropic structure: Shear viscoelasticity and related strengthening mechanism

To meet the requirements of applications, the viscoelasticity of hydrogels is usually improved by some ways, such as incorporating nanoparticles, designing network nanostructure and regulating cross-linking density. However, it is rare to improve the viscoelasticity by designing pore microstructure for hydrogels. In this work, cellulose nanocrystal (CNC)/collagen hydrogels with different pore structures (ordered tubular pores and disordered...
