“…These physical routes usually preserve the nanocellulose crystallinity and morphology better, but they are weaker and more likely to be reversible, compared to chemical modification via covalent bonds. Often, nanocellulose surface modifications via physical interactions are based on electrostatic interactions or polymer adsorption. − …”

“…One of the critical parameters for polymer composites, which governs the properties of the material, is the compatibility of the interfaces between constituting components. The interface is particularly important for nanoscale components because of their immense surface area (refs , , , , , , , , , , , , , , , , , − ). In this section, we are not delving into the vastly researched topic of how to disperse nanocellulose fillers as efficiently as possible within the continuous matrix in polymer composites.…”

Modern technology has enabled the isolation of nanocellulose from plant-based fibers, and the current trend focuses on utilizing nanocellulose in a broad range of sustainable materials applications. Water is generally seen as a detrimental component when in contact with nanocellulose-based materials, just like it is harmful for traditional cellulosic materials such as paper or cardboard. However, water is an integral component in plants, and many applications of nanocellulose already accept the presence of water or make use of it. This review gives a comprehensive account of nanocellulose–water interactions and their repercussions in all key areas of contemporary research: fundamental physical chemistry, chemical modification of nanocellulose, materials applications, and analytical methods to map the water interactions and the effect of water on a nanocellulose matrix.

“…As a result, strong interphase is required to transfer more stress from the polymer matrix to nanoparticles, 44,63,68,70 so the compatibilizer or modified nanocellulose has an essential role in the fine dispersion of nanocellulose in a polymeric matrix, especially a non-polar ones. 10,24,51,54,55,71 As noted earlier, several micro-mechanics modeling approaches, such as Halin-Tsai, Cox, and Mori-Tanaka models, 52,72,73 are common for predicting the modulus and strength of nanocellulose composites, disregarding interphase parameters. So, this issue leads to incorrect modulus estimation in the polymer nanocomposites.…”

In this study, the Ji-developed model for modeling the young modulus of nanocomposites was suggested to predict interphase thickness (Y) and modulus (Ei). The resulting model was evaluated for accuracy by comparing it to the experimental young moduli of various samples. Additionally, the effects of using a compatibilizer or modified nanocellulose on the interphase thickness and modulus of nanocellulose composites are investigated. Those samples exhibiting the highest Y and Ei parameters are TPS/NFC, PA6/NCC, and PVA/NCC, which can form hydrogen bonds with nanocellulose hydroxyl groups due to their ability to form hydrogen bonds. When compatibilizers are applied to nanocomposites or modified nanocellulose is applied in the polymer matrix, interphase parameters increase. In PLA/NFC composites, MA coupling agents were used to increase Y by 4000%, while Ei increased by 1045%. Moreover, the Y and Ei of CNCs modified with aminopropyl triethoxysilane (APS) in polyamide-6/NCC increased from 0.35 to 0.69 (97.14%) and 35.26 to 58.7 (66.47%). The Ji model was also investigated with and without considering the interphase thickness. As a result, the model became better fitted to experimental young modulus results by considering the interphase parameter in nanocomposites.

“…Homogenous filler distribution in composites also depends on the matrix-filler compatibility. The addition of compatibilizers, such as MAPE, has been often used to improve compatibility between hydrophobic and hydrophilic polyethylene, eventually aiding in the improvement of mechanical properties [ 4 , 58 , 59 ]. Nevertheless, the effect of compatibilizer on ultra-high molecular weight polyethylene, in this study, was found to be insignificant in improving mechanical properties ( Table 5 ).…”

Process Optimization of Ultra-High Molecular Weight Polyethylene/Cellulose Nanofiber Bionanocomposites in Triple Screw Kneading Extruder by Response Surface Methodology

Incorporation of nanocellulose could improve wear resistance of ultra-high molecular weight polyethylene (UHMWPE) for an artificial joint application. Yet, the extremely high melt viscosity of the polymer may constrict the mixing, leading to fillers agglomeration and poor mechanical properties. This study optimized the processing condition of UHMWPE/cellulose nanofiber (CNF) bionanocomposite fabrication in triple screw kneading extruder by using response surface methodology (RSM). The effect of the process parameters—temperature (150–190 °C), rotational speed (30–60 rpm), and mixing time (30–45 min)—on mechanical properties of the bionanocomposites was investigated. Homogenous filler distribution, as confirmed by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analysis, was obtained through the optimal processing condition of 150 °C, 60 rpm, and 45 min. The UHMWPE/CNF bionanocomposites exhibited improved mechanical properties in terms of Young’s and flexural modulus by 11% and 19%, respectively, as compared to neat UHMWPE. An insignificant effect was observed when maleic anhydride-grafted-polyethylene (MAPE) was added as compatibilizer. The obtained results proved that homogenous compounding of high melt viscosity UHMWPE with CNF was feasible by optimizing the melt blending processing condition in triple screw kneading extruder, which resulted in improved stiffness, a contributing factor for wear resistance.
