“…[ 265 ] Moreover, CNF has been used as a reinforcing additive in urea‐formaldehyde resin formulations. [ 266 ] Epoxy resins have been modified using CNCs and in combination with calcium sulfate fillers, showing improvement of the adhesive properties, [ 267 ] as well as allowing pressure sensitive acrylic glues. [ 268 ] CNC‐based latex particles for adhesion and gluing were achieved through adsorption with MC to produce MC‐coated CNCs.…”

In the effort toward sustainable advanced functional materials, nanocelluloses have attracted extensive recent attention. Nanocelluloses range from rod‐like highly crystalline cellulose nanocrystals to longer and more entangled cellulose nanofibers, earlier denoted also as microfibrillated celluloses and bacterial cellulose. In recent years, they have spurred research toward a wide range of applications, ranging from nanocomposites, viscosity modifiers, films, barrier layers, fibers, structural color, gels, aerogels and foams, and energy applications, until filtering membranes, to name a few. Still, nanocelluloses continue to show surprisingly high challenges to master their interactions and tailorability to allow well‐controlled assemblies for functional materials. Rather than trying to review the already extensive nanocellulose literature at large, here selected aspects of the recent progress are the focus. Water interactions, which are central for processing for the functional properties, are discussed first. Then advanced hybrid gels toward (multi)stimuli responses, shape‐memory materials, self‐healing, adhesion and gluing, biological scaffolding, and forensic applications are discussed. Finally, composite fibers are discussed, as well as nanocellulose as a strategy for improvement of photosynthesis‐based chemicals production. In summary, selected perspectives toward new directions for sustainable high‐tech functional materials science based on nanocelluloses are described.

“…Their widths and lengths vary from 5 to 20 nm and from 100 nm to 1-2 µm respectively [28]. CNCs have been used both in modi ed and unmodi ed forms for the development of products for several years, useful in commercial and industrial elds [29][30][31]. Cellulose nanocrystals extracted from abundant cellulose nano-llers having strength-to-weight ratio have been used as reinforcing agent for epoxy composites [32,33].…”

Bio-based epoxy resins are being used due to their green chemistry. They have better properties than petroleum-based epoxy resins. Recently, environment friendly nanomaterials have been used for different industrial applications. Cellulose nanocrystals (CNCs) are among the best naturally occurring materials.Therefore, the surface of cellulose nanocrystals are modi ed by eugenol-based silane coupling agent (EBSCA). Chemical composition and surface morphologies of CNCs were analyzed and characterized by FTIR, AFM, SEM, TEM and 1 H-NMR. The SEM and AFM results con rmed eugenol-based silane coupling agent was successfully grafted on cellulose nanocrystals. Modi ed CNCs demonstrated an excellent tensile strength (2190 MPa) and modulus (16.00 MPa), as well as storage modulus (1622 MPa) exhibited by 1wt% modi ed cellulose nanocrystals composites. Additionally, modi ed CNCs displayed hydrophobic behavior (CA=102 ± 2°). The corresponding modi ed CNCs have signi cant applications in combination of high stiffness and strength to the epoxy resins. This study lays a foundation towards full bio-based, environment friendly polymers fabrication and consumptions most desirable in adhesive and mechanical industrial elds.

This research article describes the results of nano-silica composites filled with different epoxy contents containing nano-SiO 2 particles from (5-25 wt%). Reinforcing hybrid composites enhance thermal and mechanical properties to achieve vital and sustainable products. Silica-based nanocomposites with high purity were prepared and used for the surface modification of nanosized silica particles. The surface structure's composition and physical properties of modified nano-SiO 2 particles were characterized through Fourier transferred infrared spectrometer, X-ray photoelectron spectroscopy, thermogravimetric analyzer, and scanning electron microscopic. Silica-based nanocomposites were prepared by incorporating of modified nano-SiO 2 as an enhancing filler.The morphology of fracture surface and dynamic mechanical properties were investigated. Results showed that the silica-based epoxy nanocomposites are bearing a long chain structure that could improve the compatibility of silica nanocomposites with epoxy resin and contribute to a better dispersion state in the matrix, which enhanced the overall performance of epoxy-cured products.
