Acidified ZnCl2 molten salt hydrate systems as hydrolytic media for cellulose I and II nanocrystal production: from rods to spheres

Chengpeng Shen et al.

Summary: This study explored environmentally friendly and cost-effective methods for producing nanocelluloses with controllable morphology. By treating microcrystalline cellulose with acidified zinc chloride molten salt hydrates, rod and sphere-shaped cellulose I and II nanocrystals were obtained. The levels of cellulose swelling and hydrolysis could be controlled by adjusting the concentration of HCl and ZnCl2. The resulting nanocelluloses exhibited different sizes and properties, with improved crystallinity and thermal stability observed at higher HCl concentrations. The spherical nanocellulose II showed excellent suspension stability and emulsifying ability to stabilize oil/water Pickering emulsions. This study provides a sustainable method for producing nanocelluloses with tailored characteristics and broad application potentials.

Visualizing Degradation of Cellulose Nanofibers by Acid Hydrolysis

Panagiotis Spiliopoulos et al.

Summary: The process of cellulose hydrolysis involves an intermediate semi-fibrous stage before forming objects resembling cellulose nanocrystals in a solid/gas system. The length of these nanocrystal-like objects is well correlated with molar mass and X-ray diffraction shows a slight increase in crystallinity index as hydrolysis proceeds. This research provides a modern visual complement to over a century of cellulose degradation studies.

Colloidal stability of cellulose nanocrystals in aqueous solutions containing monovalent, divalent, and trivalent inorganic salts

Tianchi Cao et al.

Summary: The aggregation kinetics and surface charging properties of rod-like sulfated cellulose nanocrystals (CNCs) in aqueous suspensions with monovalent, divalent, or trivalent inorganic salts were investigated. The phenomenon of charge neutralization and charge reversal was observed with divalent and trivalent salts, impacting the colloidal stability of the CNCs significantly. These findings have important implications for applications of CNCs in nanotechnology and materials science.

Confined Chemical Transitions for Direct Extraction of Conductive Cellulose Nanofibers with Graphitized Carbon Shell at Low Temperature and Pressure

Duan-Chao Wang et al.

Summary: By controlling the continuous reaction process and isolating oxygen, this research successfully extracted intrinsically conductive cellulose nanofibers from biomass at a low temperature. The synthesis of large-scale twisted graphene films from CNFene suspensions offers new possibilities for applications in energy storage, catalysis, and sensing, while also saving a significant amount of energy compared to traditional methods.

Redispersion Strategies for Dried Cellulose Nanofibrils

Malin Nordenstrom et al.

Summary: The potential for large-scale applications of cellulose nanofibrils is constrained by the challenge of maintaining their nanoscale dimensions after drying. However, the study demonstrates that redispersion of dried CNFs can be achieved effectively through strategies such as increasing charge density or utilizing fractionated lignin as a redispersing agent. Additionally, drying CNFs in the form of nanopapers facilitates easier redispersion without the need for a redispersing agent, maintaining excellent mechanical properties similar to those of never-dried CNFs.

Thermoresponsive and Injectable Composite Hydrogels of Cellulose Nanocrystals and Pluronic F127

Eren Kushan et al.

Summary: Cellulose nanocrystals and temperature responsive Pluronic F127 were used to create composite hydrogels with varying concentrations of CNC, leading to changes in micellization and gelation behavior. At low concentrations, the composite gel became softer and more deformable, while at high concentrations, the CNC formed its own network to increase toughness. The composite gels showed potential for smart drug delivery systems and adaptive biolubricants.
