“…This indicates the effective extraction of lignin and hemicellulose during the production of CNC by acid hydrolysis. IR spectra show that the chemical structure of CNC is similar to that of MCC, and that acid hydrolysis does not destroy the chemical structure of MCC (Trache et al 2014;Benyoussif et al 2015). The obtained result is in good agreement with the study (Kian et al 2017).…”

The main focus of this study was to introduce a natural microcrystalline cellulosic raw material source from the residue of sunflower seeds, after oil extraction. For this purpose, the conventional method of organosolvent oxidation was changed to a "soft" method where microcrystalline cellulose (MCC) was extracted from sunflower seed husk (SFH) and the characterization of MCC and cellulose nanocrystals (CNCs) were carefully carried out. In this method, the concentration of acetic acid and hydrogen peroxide required for the preparation of peroxyacetic acid (PAA) was reduced by two times. The physico-chemical characterization, particle size, optical properties, chemical and crystal structure, surface morphology, and thermal stability of MCC and CNC were studied. The FTIR analysis, revealed the structural similarity of all derivatives of cellulose. Surface morphology was monitored with SEM, and the surface of MCC fibers was rough, and the morphology of cellulose nanocrystal (CNC) was fine, smooth and rod-like (overlapping each other) appearance, CNC film surface was found to be brown was filled with nano fibrils. The XRD analysis and determination of average particle size revealed that the MCC had a CI of 72.9%, a coherent scattering length (CSL) of 2.9 nm, and an average particle size of 1971 nm along the fibers, and a width of 266 nm. The acid hydrolysis resulted in the reduction of length of CNCs by 4 times and the width was reduced about 5 times. At the same time there observed an increase in the crystallinity index (CI) value. It was found that cellulose materials were destroyed at temperatures between 200ₒС and 358ₒС. Overall, it was concluded that sunflower seed husk was considered as a potential source for CNCs and the method employed for the extraction of cellulose from agricultural biomass waste was cost effective and environmentally benign.

“…However, when the nano‐filler content excesses 4 wt%, TS would decrease gradually and the negative effect derived from CMCNCs is more serious than that of CMCNFs. Compared to previous literature reports, the unmodified CNFs increased the TS of the CMC film by 23% when the addition amount was 5% 25 and the unmodified CNCs increased the TS of CMC film by 47% when adding amount is 10% 43 . The TS increase is due to the tight network formed by the strong interactions (inter‐ and intra‐molecular hydrogen bonding) between nanocellulose and CMC matrix 44,45 .…”

In this work, carboxymethyl cellulose (CMC) with low substitution degree, followed by different posttreatments, was applied to prepare treelike CMC nanofibrils (CMCNFs) and rodlike CMC nanocrystals (CMCNCs), and their performance in CMC composite film was evaluated simultaneously. From transmission electron microscopy results, it was found that the treelike CMCNCFs exhibited a lager aspect ratio compared to the rodlike CMCNCs. As for reinforcing CMC film, 4 wt% was the best adding amount, at this time, the tensile strength of CMC/CMCNFs and CMC/CMCNCs composite films was increased by 72.1% and 47.3%, respectively. Moreover, adding these nanofillers to CMC also could enhance the thermal stability of composite films slightly, while the transmittance of composite films was reduced at the same time. In addition, CMC/CMCNFs film was designed as a packaging box to determine its performance. Therefore, this study could reveal the differences of properties for composites with different types of nanocellulose and provide a foundation for further application of nanocellulose.

“…Secondly, the tiny dimensions of nanocellulose imply a high exposure to its surroundings. The issue of biodegradation has been emphasized in studies in which nanocellulose was used in composite structures with other natural film-forming materials (Lu et al 2008;Ma et al 2008;Cheng et al 2009;Wan et al 2009;Azeredo et al 2010;Bras et al 2010;Khan et al 2010Khan et al , 2012Khan et al , 2014bSiro and Plackett 2010;da Silva et al 2012;Hassan et al 2012;Johnsy and Siddaramaiah 2012;Tang et al 2012;Baheti and Militky 2013;ChingaCarrasco et al 2013;Ollier et al 2013;Bhardwaj et al 2014;Dehnad et al 2014a;Fortunati et al 2014;Ghaderi et al 2014;Khalil et al 2014;Kumar et al 2014;Marais et al 2014;Reddy and Rhim 2014;Song et al 2014;Yang et al 2014;Azizi Samir et al 2015;Feng et al 2015a;Figueiredo et al 2015;Honorato et al 2015;Lavoine et al 2015;Li et al 2015a;Lu et al 2015;Youssef et al Please note that the lengths of some NFC and especially BC can be many times longer than what is represented in the figure.

This review article was prompted by a remarkable growth in the number of scientific publications dealing with the use of nanocellulose (especially nanofibrillated cellulose (NFC), cellulose nanocrystals (CNC), and bacterial cellulose (BC)) to enhance the barrier properties and other performance attributes of new generations of packaging products. Recent research has confirmed and extended what is known about oxygen barrier and water vapor transmission performance, strength properties, and the susceptibility of nanocellulose-based films and coatings to the presence of humidity or moisture. Recent research also points to various promising strategies to prepare ecologically-friendly packaging materials, taking advantage of nanocellulose-based layers, to compete in an arena that has long been dominated by synthetic plastics. Some promising approaches entail usage of multiple layers of different materials or additives such as waxes, high-aspect ratio nano-clays, and surface-active compounds in addition to the nanocellulose material.While various high-end applications may be achieved by chemical derivatization or grafting of the nanocellulose, the current trends in research suggest that high-volume implementation will likely incorporate water-based formulations, which may include water-based dispersions or emulsions, depending on the enduses.

As of November 2016, a search of this combination of terms showed about as many publications since the start of 2015, compared to all preceding years combined. Given such an acceleration of research around the world, it makes sense to ask whether this high amount of research effort has yet borne significant fruit. In light of this question, the emphasis of this review article is on research publications that shed light on known challenges to the successful implementation of nanocellulose products to enhance the performance of packaging.In principle, a nano...
