Cellulose nanocrystals (NCC) and cellulose nanofibrils (CNF) were obtained by a single step process, with synergy between 64% sulfuric acid hydrolysis and high shear from ultra-turrax stirring, which is an advantageous process for disintegrating cellulose microcrystalline and also may improve the hydrolysis process. The surface modification on the cellulose was performed by the sol-gel process, in which the sulfate groups from hydrolysis were replaced by nanoparticles of zinc oxide, which led to the increase of up to 54C Tonset, according to thermogravimetric analysis (TGA) results. The morphology and crystallinity degree were characterized by Helium Ion Microscopy (HIM), atomic force microscopy (AFM) and X-ray diffraction. In addition, the ZnO band was observed in Fourier transform infrared spectroscopy, furthermore, the change in the zeta potential confirmed the cellulose modification. The changes in the values of proton spin-spin relaxation time for the systems showing the confined hydrogen in the rigid domains, confirmed the results observed with the aforementioned techniques, for both cellulose after hydrolysis and ZnO modified cellulose, suggesting that ZnO disrupted crystal formation in cellulose.

“…Reported studies on cellulose nanofibrils (CNF), derived from different cellulose sources including bleached wood fiber, cotton, and agricultural residues show a yet untapped opportunity for uses in diverse applications such as in reinforcement of nanocomposites with thermoplastic and thermoset polymers, membranes, coatings, packaging, and film materials . Large scale production of CNF is possible by the combined effects of chemical, enzymatic, and mechanical treatments such as grinding, high‐pressure homogenization, and microfluidization …”

Lignocellulosic nanofibrils (LCNF) are produced from a single source of unbleached, oxidized wood fibers by serial disintegration, high‐pressure microfluidization, and homogenization. Sequential centrifugation enables fractionation by fibril width (≈5, ≈9, and ≈18 nm). LCNF residual lignin of high molecular mass reports together with the finest fraction (LCNF‐fine), whereas the more strongly cellulose‐bound lignin, of relatively lower molecular mass, associates with the coarsest fraction (LCNF‐coarse). Hot pressing softens the amorphous lignin, which fills the interstices between fibrils and acts as an in‐built interfacial cross‐linker. Thus, going from the LCNF‐fine to the LCNF‐course films, it is possible to obtain a range of values for the structural consolidation (density from 0.9 to 1.2 g cm−3 and porosity from 19% to 40%), surface roughness (RMS from ≈6 to 13 nm), and strength (elastic modulus from 8 to ≈12 GPa). The concentration of free hydroxyl groups controls effectively the direct surface interactions with liquids. The apparent surface energy dispersive component tracks with the total surface free energy and appears to be strongly influenced by the higher porosity as the fibril lateral size increases. The results demonstrate the possibility to tailor nanofibril cross‐linking and associated optical and thermo‐mechanical performance of LCNF films.

“…Moreover, the broad peak at 3442 cm −1 belongs to the stretching vibration peak of hydroxyl groups (—OH) . In the XRD patterns of CEC/CNF membranes, three diffraction peaks can be observed at 10.4°, 18.0°, and 21.0°, which can be attributed to the regularity of the rigid β‐ d ‐glucosamine repeat units . Compared to pristine CEC with a relatively high crystallinity of over 50%, the CEC/CNF/PLLA membranes have a crystallinity of 38% (Table ) .…”

Lithium (Li) metal batteries are promising candidates in next‐generation high‐power energy storage devices. However, Li dendrite growth induces great safety issues. Herein, inspired by the high electrolyte uptake, high polarity of the cellulose derivative, and excellent mechanical properties of poly‐l‐lactic acid (PLLA), a sustainable multifunctional gel polymer electrolyte (GPE) through coating a thin PLLA film on the natural polymer is proposed for Li dendrite suppression and cycling stability improvement. In addition, PLLA film coating can also enhance the thermal stability and interfacial interaction between the PLLA‐coated GPEs and Li metal, thus improving the safety of the batteries. Due to these unique beneficial features, the green GPEs enable stable cycling of the Li metal anode with an enhanced Li+ transference number and coulombic efficiency during extended cycles and increases the lifetime by inhibiting short‐circuit failures even under a high energy density and extensive Li metal deposition.
