“…Currently, CNF requires a high production cost, especially at industrial levels. The energy consumption related to the production of CNF is still an issue that hampers the scale-up production of this material [94]. Despite many different sources of CNF being discovered, the cost of industrial production continues to be a challenge that also needs attention.…”

In recent years, cellulose nanofiber (CNF) has become an avidly researched material in cutting edge research fields involving prominent researchers, both in academia and industry. This has become an exciting time reaching beyond just scientific curiosity as CNF is beginning to enter various marketplaces. CNF shows unique and potentially useful features, which includes abundance, high specific surface area, renewability, high strength, eco-friendliness and high crystallinity. It is an excellent material for polymer reinforcement. Many studies have been conducted to understand the effects of CNF as a filler in polymer composites. Interestingly, most CNF polymer composites have shown a better mechanical performance compared to the neat base polymer. Thus, this enhances the application of CNF into reinforced polymer composites in several industries such as automotive, packaging, medical implant, electronics, building material and paper. Therefore, in this review, the performances of CNF polymer composites are carefully evaluated. Beyond that, several factors influencing the performance of these composites are discussed.

“…The preparation and functionalization of nanocelluloses are now widely investigated for applications including functional nanopapers, 27,28 optoelectronics, 29,30 antibacterial coatings, 31,32 packaging, [33][34][35] mechanically reinforced papers, 36,37 and polymer composites, [38][39][40] tissue scaffolds, 41,42 drug delivery, 43,44 biosensors, 45,46 energy storage, 47,48 catalysis, 49,50 and environmental remediation. [51][52][53] Due to the ever-evolving need for adaptable solutions to newly emerged sustainability challenges, such as inaccessibility to clean water, lack of efficient energy, and threats to marine ecosystems and life on land, interest in nanocelluloses and their structure-property relationships has arisen. As a result of their large surface area with copious active sites, the surface of nanocelluloses may be chemically modified with a variety of functional groups, enabling tailorable physical and chemical properties.…”

“…Mechanical, enzymatic, and/or chemical treatments have been used to break down native cellulose into nanostructured cellulose materials among which cellulose nanocrystals (CNC), 13 cellulose nanofibrils (CNF), 25 bacterial nanocellulose (BNC), and more recently, hairy cellulose nanocrystals (HCNC), 26 are common. The preparation and functionalization of nanocelluloses are now widely investigated for applications including functional nanopapers, 27,28 optoelectronics, 29,30 antibacterial coatings, 31,32 packaging, 33–35 mechanically reinforced papers, 36,37 and polymer composites, 38–40 tissue scaffolds, 41,42 drug delivery, 43,44 biosensors, 45,46 energy storage, 47,48 catalysis, 49,50 and environmental remediation 51–53 …”

Nanocelluloses, nanoscale cellulosic particles or fibrils, are an appealing class of nanomaterials with enormous potential for sustainable development. They have great promise to target some of the 17 Sustainable Development Goals outlined by the United Nations. Nanocelluloses are derived from the most abundant biopolymer in the world, cellulose, which have multiple hydroxyl groups on their surface, enabling a vast range of chemical modifications. The interplay between the chemical structure and physicochemical properties of nanocelluloses is crucial to engineering the next generation of green, functional nanomaterials. In this review paper, we provide a comprehensive account of the structure–property relationships in nanocelluloses, which may establish the basis for the design of precision bio‐based materials. Chemical modifications of nanocelluloses, including hydrolysis, oxidation, esterification, amidation, and polymer grafting, provide an array of chemical and physical properties that open opportunities in a diverse spectrum of applications. We review how chemical modifications affect the physicochemical properties of nanocelluloses, such as thermal stability, hydrophobicity, and dispersibility in nonpolar media. Understanding nanocellulose chemical structure–property relationships is integral to the development of sustainable material platforms based on the most renewable biopolymer on earth.

“… 3 Besides that, there are other major problems found with the use of these methods which are incomplete precipitation of the contaminant and the formation of large volumes of sludge that is known to be difficult to be filtered and disposed of. 4 Among the different treatment methods used for chemical decontamination, the adsorption method is considered the simplest and most convenient approach. 5 Adsorption is a surface process that involves the accumulation of a gas or liquid onto a solid phase which is called the adsorbent.…”
