“…In the images of pristine cellulose-based cotton ( Fig. 7 ) the characteristic fibers of this material are evident ( Ibrahim et al., 2017 ; P. Wang et al., 2018 ). A smooth film of TiO 2 particles was observed on the cotton fabrics with TiO 2 -S1 and TiO 2 -S2 although the film presented several clusters (some highlighted by red circles) and cracks (some highlighted by red arrows).…”

“…However, hospital cotton items are usually washed and reused. In the latter case, the cotton fabric covered with TiO 2 generally presents a low level of wash resistance due to the poor adhesion between the TiO 2 particles and the fibers ( Dastjerdi, Montazer & Shahsavan, 2009 ; Wang et al., 2018 ).…”

“…The material used to support TiO 2 can significantly contribute to promoting the interaction between viruses and particles. Cellulose-based fabrics such as cotton and non-woven fabrics have been widely studied for the application of titanium dioxide hydrosols, resulting in fabrics with photocatalytic and self-cleaning properties ( Ahmad, Kan & Yao, 2019 ; Ibrahim et al., 2017 ; N. A. Ibrahim et al., 2018 , 2018 , 2018 ; Moon et al., 2020 ; Rashid, Simoncic & Tomsic, 2021 ; Tan, Gao, Guo, Guo & Long, 2013 ; Wang, Dong, Li, Li & Bian, 2018 ). Properties such as porosity, flexibility and layered surface structure contribute to the incorporation of nanoparticles in its structure, providing new functional properties ( Ahmad et al., 2019 ).…”

Antiviral hydrophobic cellulose-based cotton or non-woven fabrics containing mesoporous TiO 2 particles were developed for potential use in healthcare and in other contaminated environments. Hydrosols made with the sol-gel method using two different amounts of the Ti precursor were applied to cotton and non-woven fabrics and their virucidal effect on Murine Coronavirus (MHV-3) and Human Adenovirus (HAdV-5) was evaluated under indoor light irradiation. The results show 90% reduction of HAdV-5 and up to 99% of MHV-3 in non-woven fabric, and 90% reduction of MHV-3 and no reduction of HAdV-5 in cotton fabric. The antiviral activity was related to the properties of the TiO 2 powders and coatings characterized by BET surface area, DRX, DLS, FTIR, DRS, SEM, TEM and water contact angle. The hydrophobic characteristic of the treated fabrics and the high surface area of the TiO 2 particles favor interaction with the virus, especially MHV-3. These results demonstrate that non-woven fabric and cotton, coated with TiO 2 , can be highly effective in preventing contamination with MHV-3 and HAdV-5 viruses, particularly for applications in healthcare indoor environments.

“…The widely used antimicrobial agents for textiles include chitosan, metal salts, halogenated phenols, and N-halimanes, which can be applied to the fabric surface using conventional pad-dry-cure method, spraying, exhaustion, foam-application, and surface grafting. In particular, metals and metal oxide nanoparticles (e.g., silver, zinc oxide, and titanium dioxide) are extensively used for surface functionalization of cotton fabrics to impart antimicrobial activity, UV protection [ 92 , 93 , 94 , 95 , 96 ], and photocatalytic self-cleaning behavior [ 97 , 98 , 99 , 100 ]. Superhydrophobicity (lotus effect) is also imparted to the fabric surface for improved self-cleaning behavior, and liquid droplets that fall onto modified surfaces tend to entrap soil/dirt particles and roll off the fabric surface [ 91 , 98 ].…”

Petroleum-based synthetic plastics play an important role in our life. As the detrimental health and environmental effects of synthetic plastics continue to increase, the renewable, degradable and recyclable properties of cellulose make subsequent products the “preferred environmentally friendly” alternatives, with a small carbon footprint. Despite the fact that the bioplastic industry is growing rapidly with many innovative discoveries, cellulose-based bioproducts in their natural state face challenges in replacing synthetic plastics. These challenges include scalability issues, high cost of production, and most importantly, limited functionality of cellulosic materials. However, in order for cellulosic materials to be able to compete with synthetic plastics, they must possess properties adequate for the end use and meet performance expectations. In this regard, surface modification of pre-made cellulosic materials preserves the chemical profile of cellulose, its mechanical properties, and biodegradability, while diversifying its possible applications. The review covers numerous techniques for surface functionalization of materials prepared from cellulose such as plasma treatment, surface grafting (including RDRP methods), and chemical vapor and atomic layer deposition techniques. The review also highlights purposeful development of new cellulosic architectures and their utilization, with a specific focus on cellulosic hydrogels, aerogels, beads, membranes, and nanomaterials. The judicious choice of material architecture combined with a specific surface functionalization method will allow us to take full advantage of the polymer’s biocompatibility and biodegradability and improve existing and target novel applications of cellulose, such as proteins and antibodies immobilization, enantiomers separation, and composites preparation.

“…In case of treating with both KBr (0.06 molL -1 ) and fixing agent, QSP and LSP% values rose with increasing concentration of fixation agent, and they were closed to 500 mgg -1 and 100%, respectively at the concentration of 70 gL -1 . This was because fixing agent was prepared through the amidation of the condensate resin of polyethylene-polyamine with dicyandiamide to introduce the hydroxymethyl groups, which could react with the hydroxyl groups of cotton fiber to form stable ether bondings (Wang et al 2018), thus limiting Ag3PO4 particles from moving out of the fiber. Besides, fixing agent could produce a polymer layer near the fiber surface to encapsulate Ag3PO4 particles for reducing their ability to diffuse out of the fiber during water washing.…”

Cotton fabric was first modified with citric acid to introduce surface carboxyl groups, which then coordinated with Ag+ ions to prepare the Ag3PO4 finished cotton fabric through further reacting with PO43- ions using an industrialized pad-dry-cure process. Increasing surface carboxyl groups could significantly enhanced the loaded content of Ag3PO4. The padding process could more strongly fix Ag3PO4 on fabric than the conventional dipping method. The Ag3PO4 finished cotton fabric showed higher photocatalytic capacity than pure Ag3PO4 particles owing to the synergetic effect of the Ag complex with the carboxyl groups on the fabric. Moreover, the treatment of KBr and fixing agent further improved the the stability and anti-photocorrosion performance of the samples. Importantly, the finished fabric also exhibited better self-cleaning performance for Reactive Red 195 as a model stain under varied irradiation. The dye was found to be decomposed and mineralized on the finished fabric under artificial or solar irradiation.
