“…Due to its versatility, biodegradability and ability to substitute petroleum-based fibres for nanoporous membranes (Lu et al 2018 ), cellulose is a potential material for disposable membrane air filters. Cellulose can be extracted from lignocellulosic biomass and accounts for more than 90% of plant material and 40–45% of wood (Correia et al 2015 ; Haldar and Purkait 2020 ; Garcia et al 2021; Stanislas et al 2020 ). It is embedded in the complex network of hemicellulose and lignin and its fibrous structure plays an essential role in the structural integrity of plant cell walls (Phuong et al 2022 ), as shown in Fig.…”

“…Nanocellulose-based filter media, which could replace petroleum-based masks and respirators (FFP2 or FFP3 for European Standards and N95 or N99 for US standards) in the filtration of airborne viruses, have been intensively developed recently around the world as an environmentally friendly solution (Liu et al 2021a , b ; Ukkola et al 2021 ; Wang et al 2019b). The preparation of cellulose nanofibrils (CNF) from cellulosic materials has several advantages such as high specific surface area, easy functionalization and high mechanical strength (Correia et al 2016 ; Stanislas et al 2022 , 2020 ; Xiong et al 2021 ), which improves the capture efficiency of small particles due to the nanoscale of the pores (Ukkola et al 2021 ). Recently, CNF have been used to prepare filter media by the freeze-drying method for face masks (Mao et al 2008 ; Segetin et al 2007 ; Sim and Youn 2016 ; Ukkola et al 2021 ), water decontamination (Sehaqui et al 2016 ; Wang et al 2020 ), battery separator (Sim et al 2015 ), coating layers (Bai et al 2019 ), transparent devices (Wang et al 2020 ) and vehicle exhaust treatment (Liu et al 2021a , b ), as shown in Table 5 .…”

The controversy surrounding the transmission of COVID-19 in 2020 has revealed the need to better understand the airborne transmission route of respiratory viruses to establish appropriate strategies to limit their transmission. The effectiveness in protecting against COVID-19 has led to a high demand for face masks. This includes the single-use of non-degradable masks and Filtering Facepiece Respirators by a large proportion of the public, leading to environmental concerns related to waste management. Thus, nanocellulose-based membranes are a promising environmental solution for aerosol filtration due to their biodegradability, renewability, biocompatibility, high specific surface area, non-toxicity, ease of functionalization and worldwide availability. Although the technology for producing high-performance aerosol filter membranes from cellulose-based materials is still in its initial stage, several promising results show the prospects of the use of this kind of materials. This review focuses on the overview of nanocellulose-based filter media, including its processing, desirable characteristics and recent developments regarding filtration, functionalization, biodegradability, and mechanical behavior. The porosity control, surface wettability and surface functional groups resulting from the silylation treatment to improve the filtration capacity of the nanocellulose-based membrane is discussed. Future research trends in this area are planned to develop the air filter media by reinforcing the filter membrane structure of CNF with CNCs. In addition, the integration of sol–gel technology into the production of an air filter can tailor the pore size of the membrane for a viable physical screening solution in future studies.

“…The peaks at 1635 cm −1 represent the bending vibration peak of -OH in water molecules. This was mainly caused by the absorption of water molecules by the hydrophilic groups in the cellulose molecules [32]. In addition, the peaks around 1202, 1162, and 1060 cm −1 represent the shear vibration peak, asymmetric vibration peak, and stretching vibration peak generated by CH 2 , C-O-C, and C-O on the cellulose epoxy structure C 6 , respectively [33,34].…”

Fabrication and Characterization of Cellulose Nanofiber Aerogels Prepared via Two Different Drying Techniques

et al. 2020

Studies on the influence of drying processes on cellulose nanofiber (CNF) aerogel performance has always been a great challenge. In this study, CNF aerogels were prepared via two different drying techniques. The CNF solution was prepared via existing chemical methods, and the resultant aerogel was fabricated through supercritical CO2 drying and liquid nitrogen freeze-drying techniques. The microstructure, shrinkage, specific surface area, pore volume, density, compression strength, and isothermal desorption curves of CNF aerogel were characterized. The aerogel obtained from the liquid nitrogen freeze-drying method showed a relatively higher shrinkage, higher compression strength, lower specific surface area, higher pore volume, and higher density. The N2 adsorption capacity and pore diameter of the aerogel obtained via the liquid nitrogen freeze-drying method were lower than the aerogel that underwent supercritical CO2 drying. However, the structures of CNF aerogels obtained from these two drying methods were extremely similar.

“…Researchers are now interested in the implementation of bio-composite materials with plant fibers as reinforcements. As a result, mineral and synthetic fibers are replaced by long plant fibers [5] and short plant fibers [6] for the implementation of biocomposites. From then on, the search for the material with optimal rigidity becomes a perpetual watch in the design of bio-composites.…”

This work focuses on the optimal design of the woven fabrics made from Raphia vinifiera, fiber, and their contribution as reinforcing element in the epoxy matrix. The work is done alternately experimentally and theoretically. The woven made of canvas, twill and satin armor are characterized in traction according to the ISO13934-1 standard [1]. A predictive mathematical model of Young's modulus of the woven with the greatest rigidity is established. The woven reinforcement composite made is characterized in traction and bending according to EN ISO 527-5 [2] and NF EN ISO 14125 [3] standards. In order to determine the reinforcement rate which gives the highest young modulus of the material, the gradient method was applied on some prediction equations of Young's modulus of composite material. Then find the prediction equation that best corresponds to the composite made. The results showed that mathematical modeling works corroborates with experimental works. On the woven fabrics the canvas armor has the highest Young's modulus in the warp and weft direction (2.429, 21.164 GPa). Followed by twill (2315, 18 741 GPa) and satin (2184, 18.54 GPa). On the composite, the reinforcement rate from which the material is optimized is 50%. The composite young's moduli in the warp and weft direction resulting from the tensile and bending tests of the composite are respectively (3.644, 7.31 GPa) and (1.802, 4.52). In a nutshell, this work presents the theoretical and experimental aspect of the best material which can be obtained with R. vinifiera fiber with respect to its Young modulus.
