Summary: This study aimed to isolate cellulose nanofibers (CNF) from sisal fibers and enhance their hydrophobic characteristics through acetylation. The sisal fibers were pre-treated with alkaline hydrogen peroxide (AHP) before being acetylated with acetic anhydride. Acetylated and non-acetylated CNF were then obtained by mechanically defibrillating the pre-treated fibers. Various analyses showed that the acetylated CNF (ACNF) exhibited a more stable suspension and better dispersion in acetone compared to CNF. The acetylation process also reduced the crystallinity index of CNF and increased its hydrophobicity without compromising thermal stability. ACNF extracted from sisal fibers showed great potential as a reinforcement for nanocomposites with nonpolar polymer matrices.

Summary: The study reveals that different types of nanocelluloses play various roles during emulsification, with flexible bacterial cellulose showing minimal emulsification capability, while semi-flexible cellulose nanofiber and rigid cellulose nanocrystal can effectively stabilize emulsions. The system stabilized by cellulose nanofiber is dominated by depletion effect, leading to the formation of droplet clusters easily, whereas the system stabilized by cellulose nanocrystal is characterized by the repulsive effect playing a more important role.

Summary: Cellulose nanofibers (PO-CNFs) and cellulose nanocrystals (PO-CNCs) are directly prepared from native softwood spruce and hardwood beech using the same alkaline periodate oxidation. These nanocelluloses, containing carboxy groups, exhibit good colloidal stability in water and can be used to form highly transparent films with good mechanical properties. The nanocellulose content isolated from the spruce and beech increases with reaction time, reaching optimal levels after 7 days of oxidation.

Summary: In this study, composites of polypropylene (PP) reinforced with hemp strands (HS) were prepared to investigate the impact performance of these composites. The research found that the quality of the interface plays a significant role in the impact resistance of the materials. The main contributors to crack formation are interface strength, fiber dispersion, and fiber pullout, while fiber pullout is the main contributor to crack propagation. The study also examined the water absorption behavior of the composites in different humid environments and found that water diffusion followed a Fickean behavior.

Summary: Bio-based polymers can meet the demands of society and regulations to minimize environmental impact, especially for companies seeking a smooth transition with less uncertainty. By using BioPE as the matrix, similar to HDPE, abaca-fiber-reinforced composites were obtained and compared with commercial glass-fiber-reinforced HDPE. Micromechanical models were employed to estimate the interface strength and tensile strength of the reinforcements. The addition of 8 wt.% coupling agent improved the interface strength of biocomposites, resulting in tensile properties comparable to commercial glass-fiber-reinforced HDPE composites.

Summary: The use of bio-based matrices and natural fibers as reinforcement is a strategy to obtain materials with competitive mechanical properties, costs, and environmental impacts. In this study, composites reinforced with abaca fibers and different matrices are prepared and tested. The results show that bio-polyethylene as a matrix can provide slightly higher mechanical properties than polyethylene. It is possible to obtain fully bio-based composites with mechanical properties similar to partially bio-based polyolefin or glass fiber-reinforced polyolefin.

Summary: This study successfully prepared lignin-containing cellulose nanofibrils (LCNFs) with a lignin content of up to 21% through hydrothermal treatment and high-pressure homogenization. The presence of lignin added hydrophobicity, UV-shielding capacity, and reduced water sensitivity to the LCNFs. The study also proposed a mechanism explaining how hydrothermal treatment with maleic acid facilitated the disintegration of biomass into nanoscale material. The research showed a feasible and scalable approach for the sustainable production of LCNF suspensions from agricultural residues without the need for preliminary partial delignification.

Summary: The potential of TEMPO-mediated oxidation to produce CNFs is hindered by the use of expensive and environmentally harmful catalysts. This research identifies key parameters for reusing the TMO medium and their impact on CNF quality. Contrary to previous hypothesis, concentration of salts is not a key parameter; instead, high pulp consistency during oxidation leads to better CNF quality. Reusing the reaction medium up to six times significantly reduces catalyst dose, reaction time, and effluent, resulting in a threefold increase in CNF production.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
