Cellulose nanocrystals (CNC) can be embedded within hydrogels to form tough and strong nanocomposite materials, which possess biomimetic properties from hydrogels including good biocompatibility, permeability and flexible mechanical characteristics. There are many potential applications for these strong nanocomposite hydrogels in medical devices, such as wound dressing or super absorbents. Whereas,...
Halloysite nanotubes (HNTs) were added to cellulose NaOH/urea solution to prepare composite hydrogels using epichlorhydrine crosslinking at an elevated temperature. The shear viscosity, mechanical properties, microstructure, swelling properties, cytocompatibility, and drug delivery behavior of the cellulose/HNT composite hydrogels were investigated. The viscosity of the composite solution increases...
In this work, a novel poly(ethylene glycol) (PEG)/NaOH system was successfully applied as a co-solvent for two naturally occurring polysaccharides, cellulose (Cel) and sodium alginate (Alg), to obtain biopolymeric films. Different amounts of Cel and Alg were dissolved in aqueous mixtures of PEG and NaOH, cast onto a glass plate, and cross-linked using a combination of physical and chemical cross-linking...
