Summary: Phosphorylation of nanocellulosic materials involves incorporating phosphate groups into cellulose fibers, resulting in nanofibers with high aspect ratio and surface charge. This treatment improves dispersion in water, reduces clogging and energy consumption during mechanical treatment. This review discusses preparation methods, characteristics, potential applications, and future prospects of phosphorylated nanocellulose.

Summary: The study demonstrates that ionic liquid can improve the dispersion of cellulosic nanofillers and enhance the mechanical strength of vulcanizates. As the concentration of cellulosic nanofillers and ionic liquid increases, the viscoelastic rheological behavior of the vulcanizates is also affected.

Summary: Using polysaccharide nanocrystals as fillers in biodegradable polyesters can create completely biodegradable nanocomposites. The study found that chitin nanocrystals and cellulose nanocrystals have completely different effects on the crystallization of poly(epsilon-capro-lactone) (PCL). Chitin nanocrystals retard the nucleation and overall crystallization process of PCL, while cellulose nanocrystals promote nucleation and accelerate crystal growth.

Summary: In this study, jute fibers were used as source material to produce cellulose nanofibrils (CNFs) using phosphorylation pretreatment. The relationship between the microstructure and rheology of CNF aqueous suspensions was investigated. The results showed that phosphorylation enhanced the diameter of nanofibers and improved the flame retardancy of CNF. The CNF suspensions exhibited shear-thinning behavior and gel-like viscoelastic character, and their viscoelastic properties were not affected by frequency and temperature alterations.

Summary: The morphology and length of cellulose nanofibers (CNFs) have a significant impact on their reinforcement effect in recycled paper, with higher aspect ratios leading to better reinforcement. CNFs produced by microfluidic homogenization and suitable PFI milling conditions showed the best reinforced effect, improving tensile index and burst index significantly. This study aimed to investigate the influence of CNFs on reinforcing recycled fibers.

Summary: Driven by the demand for various cationic biopolymers, the quaternization of cellulose nanofibers has been carefully investigated to control their final characteristics. The addition of sodium hydroxide (NaOH) is crucial in catalyzing the conversion of alcohol groups of cellulose, while excessive concentration inhibits the reactivity of hydroxyl groups. The addition of glycidyltrimethylammonium chloride (GTMAC) increases the yield of the reaction, but excessive amounts affect the rheological properties of the quaternizated cellulose nanofibers. The research expands the possibilities of using cellulose in cationic biopolymer applications.

Summary: The surface sulfate groups of cotton-derived cellulose nanowhiskers were quantified using three different methods. The conductometric titration and TBO adsorption methods showed similar values, while the sulfur elemental analysis method overestimated the sulfate content. The study also demonstrated the desulfation efficiency under different desulfation conditions.

Summary: Melanins are black-brown pigments with photoprotective and radical scavenging properties. This study explores the use of cellulose nanofibrils as a stabilizing agent for insoluble eumelanin, resulting in a flexible eumelanin hydrogel composite for environmental sensing and battery applications. The composite shows improved charge storage ability and pH and metal ion detection capabilities. It also exhibits stability in electrolyte zinc coin cells for over 1200 cycles, making it a promising eumelanin-based hybrid sensor/energy storage material.

Summary: Sticky rice-lime mortar has been widely used in traditional buildings, but its edible nature and complex composition restrict its large-scale use. In this study, cellulose nanocrystals were used as a substitute material to prepare lime mortars with similar properties to traditional sticky rice-lime mortar. The organization of cellulose nanocrystals and the molar percent of calcium carbonate were found to be closely related to the compressive strength of lime mortars.

Summary: Nanocellulose, a sustainable nanomaterial, has attracted increasing attention due to its versatile applications. This study investigated the viscoelasticity, thixotropy, and yielding behavior of two commonly used nanocelluloses, rod-shaped cellulose nanocrystals (CNCs) and filamentous cellulose nanofibrils (CNFs), to explore their relationship with the structure. The rheological properties of the two suspensions showed strong dependence on concentration and time. CNF suspensions exhibited stronger thixotropy and higher yield stress compared to CNC suspensions, attributed to the higher aspect ratio and stronger structural skeleton of CNF suspensions.
