Summary: Nanofibrillated cellulose (NFC) prepared from microcrystalline cellulose (MCC) via high-pressure homogenization process can be used as a coating agent to enhance the properties of paper coatings and coated paper. The optimum NFC addition of 0.30-0.40% can lead to improved performance of coated paper, such as decreased water retention value and increased tensile strength, with a relatively uniform surface structure.

Summary: Biodegradable composites (PBAT-HMNC) consisting of PBAT, thermoplastic starch, hydrophobically modified nanofibrillated cellulose (HMNC), and green surfactant were prepared and characterized. The composites exhibited excellent mechanical and barrier properties, with the highest tensile strength and lower thermal decomposition temperature. The water vapor and oxygen transmission rates were significantly reduced with the addition of 0.6 wt% HMNC, leading to prolonged preservation of Agaricus mushrooms. PBAT-HMNC composites have great potential as nanocomposite materials for packaging.

Summary: Cellulose nanomaterials, including nanofibrillated cellulose and cellulose nanocrystals, have unique properties such as sustainability, biodegradability, and biocompatibility, making them attractive for a wide range of applications. Their aqueous suspension rheology allows for the creation of viscous suspensions with shear-thinning behavior. These properties make cellulose nanomaterials valuable rheological modifiers in fluid-based applications.

Summary: A nanofibrillated cellulose-based multifunctional superhydrophobic coating (NMSC) was developed through an efficient silylation process. The NMSC exhibited nanoroughness, low surface energy, thermal stability, and unprecedented hydrophobic and self-cleaning performance. It also showed effective long-term barriers to various fluids and a certain degree of antibacterial performance. This work provides a good approach for the high-value application of cellulose and the development of ecological and sustainable multifunctional coatings.

Summary: Flexible supercapacitors have the advantages of high capacity, fast charge/discharge rate, good stability, portability, and softness. Conductive polymer polypyrrole (PPy) is an electrode material for supercapacitors due to its environmental friendliness, simple synthesis process, good conductivity, and potential for large-scale production. However, the structural rupture of pristine PPy during charge and discharge processes impairs its cycle stability. Compounding PPy with flexible substrates like cellulose can effectively weaken the inner stress and prevent structure pulverization. In this study, a smooth, uniform, and flexible PPy/cellulose composite film was successfully obtained using the electrochemical oxidation of polypyrrole on cellulose as a soft substrate. The assembled symmetric supercapacitor with the PPy/cellulose film exhibited an optimized specific capacitance of 256.1 mF cm(-2) even after 10,000 cycles at a current density of 1 mA cm(-2). The device also showed no significant capacitance loss even after 180 degrees bending. This work provides a new method to prepare flexible, low-cost, environmentally friendly, and high-performance electrode materials for energy conversion and storage systems.

Summary: Flexible electrically conductive composites based on renewable resources, specifically NFC loaded with PPy-NT, exhibited high conductivity and gravimetric capacitance, but with fast capacitance decay in a larger potential window; C-PPy-NT/NFC and MWCNT/NFC showed better cycling stability but lower capacitance. PPy-NT/NFC had the highest shielding efficiency, reaching 75%.

Summary: Carbon materials derived from bacterial cellulose were used as anodes in potassium-ion batteries. A novel composite of polypyrrole was creatively realized on the surface of bacterial cellulose nanofibers. The carbonized composite showed a high capacity and long cycling stability, attributed to nitrogen doping and defect carbon materials. This study provides a guideline for developing bacterial cellulose composites in energy storage.
