“…The earlier-mentioned materials have the potential to serve as substitutes for plastic coatings in the textile industry, hence offering improved strength and performance attributes to fiber-based materials [11]. Its coatings may be customised with certain characteristics, including hydrophobicity, antimicrobial capabilities, and resistance to ultraviolet radiation [85]. Along with this, nanocellulose has promising potential in the realm of stabilising ancient paper and archaeological fabrics.…”

In recent times, there has been a discernible focus on the development of environmentally friendly and sustainable biomaterials obtained from renewable sources. Scientists are now investigating the prospective applications of nanocellulose, a biocompatible substance derived from natural cellulose. The aforementioned substance exhibits notable characteristics, such as a substantial surface area to volume ratio, with its compatibility with biological systems and capacity to undergo degradation. Nanocellulose has the capability to undergo transformation into nanofibers and nanocrystals, so enabling the generation of diverse structures, including elongated nanofibers, suspensions, and films. In the textile industry, there is a growing need to adopt sustainable techniques in order to address and minimize the negative environmental impacts. The current focus is on the advancement of environmentally sustainable alternatives in the realm of textile production, namely cellulose-based materials. These textiles are being created using processes that aim to minimize water pollution. In addition, recent advancements in dyeing methods have used nanocellulose to effectively reduce water consumption and eliminate the need for toxic materials. Nanocellulose nanocomposites, such as nanofibrillated celluloses (NFCs) and cellulose nanocrystals (CNCs), are increasingly used as fillers in textile nanocomposites to enhance their mechanical characteristics due to their cost-effectiveness and recyclability. The advancements achieved in the field of nanocellulose-based materials and technology exhibit considerable promise in the development of ecologically friendly solutions across several industries.

“…Theoretical and practical improvements in the use of cellulose and its derivatives in the manufacture of new and high-performance materials have highlighted two primary issues: (a) when it comes to imparting significantly improved bulk properties (or even new ones) to materials in a highly effective manner, using nanostructured cellulose (nano-fibers, nano-crystals, nano-whiskers) is a wise choice; (b) chemical reactions (i.e., oxidation) applied to functionalize cellulose have proved to be a useful tool not only for expanding the range of applications, but also for boosting the specificity and lowering the negative environmental impact [ 1 , 2 , 3 ].…”

Raw cellulose, or even agro-industrial waste, have been extensively used for environmental applications, namely industrial water decontamination, due to their effectiveness, availability, and low production cost. This was a response to the increasing societal demand for fresh water, which made the purification of wastewater one of the major research issue for both academic and industrial R&D communities. Cellulose has undergone various derivatization reactions in order to change the cellulose surface charge density, a prerequisite condition to delaminate fibers down to nanometric fibrils through a low-energy process, and to obtain products with various structures and properties able to undergo further processing. Selective oxidation of cellulose, one of the most important methods of chemical modification, turned out to be a multitask platform to obtain new high-performance, versatile, cellulose-based materials, with many other applications aside from the environmental ones: in biomedical engineering and healthcare, energy storage, barrier and sensing applications, food packaging, etc. Various methods of selective oxidation have been studied, but among these, (2,2,6,6-tetramethylpiperidin-1-yl)oxyl) (TEMPO)-mediated and periodate oxidation reactions have attracted more interest due to their enhanced regioselectivity, high yield and degree of substitution, mild conditions, and the possibility to further process the selectively oxidized cellulose into new materials with more complex formulations. This study systematically presents the main methods commonly used for the selective oxidation of cellulose and provides a survey of the most recent reports on the environmental applications of oxidized cellulose, such as the removal of heavy metals, dyes, and other organic pollutants from the wastewater.
