“…Recently, other mineral and organic acids have also been utilized to produce CNCs 8,38,39,[45][46][47] . Several other preparations approaches have been developed, such as enzymatic hydrolysis [48][49][50][51] , mechanical refining [52][53][54] , ionic liquid treatment [48][49][50][51][55][56][57][58] , subcritical water hydrolysis 32,59 , oxidation method [60][61][62][63] and combined processes [64][65][66][67][68] . Keeping in mind the different synthesis strategies, one of the prime objectives of this review is to summarize and emphasize the up-to-date procedures employed to extract CNCs showing their advantages and drawbacks, that we believe will provide a strong base for the future development in this emerging area of research.…”

Cellulose nanocrystals, a class of fascinating bio-based nanoscale materials, have received a tremendous amount of interest both in industry and academia owing to its unique structural features and impressive physicochemical properties such as biocompatibility, biodegradability, renewability, low density, adaptable surface chemistry, optical transparency, and improved mechanical properties. This nanomaterial is a promising candidate for applications in fields such as biomedical, pharmaceuticals, electronics, barrier films, nanocomposites, membranes, supercapacitors, etc. New resources, new extraction procedures, and new treatments are currently under development to satisfy the increasing demand of manufacturing new types of cellulose nanocrystals-based materials on an industrial scale. Therefore, this review addresses the recent progress in the production methodologies of cellulose nanocrystals, covering principal cellulose resources and the main processes used for its isolation. A critical and analytical examination of the shortcomings of various approaches employed so far is made. Additionally, structural organization of cellulose and nomenclature of cellulose nanomaterials have also been discussed for beginners in this field.

“…Recently, cellulose bers subjected to acid hydrolysis, yield nanoscale rod-like crystalline residues, which are called cellulose nanocrystals (CNCs) 1,2 or nanocrystalline cellulose (NCC). 3,4 CNCs can be extracted from a great variety of sources, including wood pulps, 5 cotton, 6 sisal, 7 hemp, 8 ax, 8 microcrystalline cellulose (MCC), 9,10 and so on. As a nano-material, CNCs exhibits many appealing properties, such as high crystallinity, large aspect ratio, biodegradability, nano-dimensions, light weight, and large surface area.…”

“…The structural and morphological changes can be observed with the treatment of the fibers, and this is mainly due to the removal of non-cellulosic substances from the natural fibers. The significant improvements of the properties of the composites are reported after different chemical treatments along with the increase in the thermal stability of the composites reinforced with natural fibers (Singh et al, 1996;Xie et al, 2010;Xu et al, 2013;Chen et al, 2018).…”

The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability, and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.
