Summary: A new method for the synthesis of nanofibrillar cellulose/polystyrene composite is proposed, which involves ultrasonic treatment of styrene emulsion in cellulose-water solution. This method eliminates the need for additional heating and significantly reduces the synthesis time compared to previous methods. Comprehensive analysis indicates that the mechanical, physical, and biodegradable properties of the composite obtained by the ultrasonic method are comparable to those obtained by the conventional thermal method.

Summary: An increased demand for eco-friendly bio-degradable food packaging material is arising to control the worldwide environmental crises. Bio-nanocomposite films were synthesized using chitosan matrix, glycerol plasticizer, and different plant extracts. Nanofillers, nano-keratin and cellulose nanocrystals, were added to strengthen the chitosan. The combination of both nano fillers and extracts exhibited a synergistic effect, enhancing the thermo-mechanical and barrier properties of the bio-nanocomposite films for improved shelf life of packaged food.

Summary: We report the basic sheet properties of divalent phosphorylated cellulose nanofibers (CNFs) with different phosphorus contents and counterion types. The counterion exchange from sodium ions to calcium or aluminum ions greatly enhances all examined sheet properties of CNF sheets. The phosphorus content only has significant influences on conditioned tensile and fire-retardant properties. Compared to CNF sheets with monovalent carboxy groups, CNF sheets with divalent phosphate groups are superior in terms of wet tensile properties and fire-retardant properties.

Natural fiber composites have numerous advantages such as durability, low cost, low weight, high specific strength, environmental friendliness, and biodegradability. Chitosan, a natural fiber, can be processed into various forms and has been found to possess high thermal stability and good physical and chemical properties. Chitosan-based green composites have wide applicability in industries such as biomedicine, cosmetology, papermaking, wastewater treatment, agriculture, and pharmaceuticals.

Summary: High mechanical performance spun bionanocomposite fibers of chitosan (CHI) filled with cellulose nanofibers (CNFs) were achieved through gel spinning, leading to improved crystallinity and mechanical properties. Increasing the CNF content up to 0.4 wt% in the CHI solution significantly enhanced Young's modulus and tensile strength of the fibers, while further increases in CNF content slightly impacted mechanical parameters due to potential disruption of the CHI matrix hydrogel network. Overall, the addition of 0.4 wt% CNFs into 4 wt% CHI formulations showed optimal compatibility and interface, resulting in bionanocomposite fibers with outstanding mechanical properties.

Summary: This study prepared aligned aramid nanofiber/poly(vinyl alcohol) (ANF/PVA) nanocomposites with a nanofiller volume fraction of 48%, showing improvements in mechanical strength and stiffness due to effective stress transfer between aligned ANFs and PVA. The damping properties varied depending on different dissipation modes activated and loading angles relative to the nanofiber alignment direction, leading to viscoelastic properties exceeding conventional limits. Deepening the understanding of anisotropic dynamic mechanical responses is crucial for designing aligned nanocomposite materials for mechanical and electronic applications.

Summary: Blending chitosan with MMT nanoplatelets enhanced mechanical properties and hydrophobicity, while blending with SPT nanoneedles had a less significant impact. In the chitosan/SP system, MMT disrupted biopolymer chain interactions, leading to reduced mechanical properties, while SPT enhanced mechanical properties due to better dispersion.

Summary: In this study, a simple model is proposed to predict the Young's modulus of polymer composites containing cellulose nanocrystals (CNCs). The model is validated by experimental results and shows good agreement with measured values. Various factors such as interphase thickness, volume fraction of interphase regions, densities of polymer matrix and CNC, and CNC size are investigated for their effects on the Young's modulus. Thinner CNCs and thicker interphase contribute to higher modulus, while the volume fraction of interphase regions has the least influence on the nanocomposite modulus.

Summary: This study investigated the thermal and structural properties of multilayer composites based on chitosan and different polyanions. The results showed that the type of polyanion used influenced the thermal degradation and crystallization behavior of the composite materials. Strong acid salts as counterions to chitosan led to strong interactions between layers, while weak polyacid salts resulted in weaker PEC formation.
