“…The fiber is defined as a substrate of natural origin, which its length/diameter ratio is more than 1:200 [26] "Nanofibers could be defined as the fibers which have their diameters in nanometric range" [27] The main sources Green composites based on natural fibers compared to petroleum-based fiber composites [28,29] Nanofibers are generally classified based on their composition into metal oxides, polymers, metals, carbon, ceramics, and hybrid [30] Main categories of natural fiber Main types of nano-lignocellulose fibers 1-Mineral fibers (asbestos, basalt, and brucite) 1-Lignocellulose nanofiber [31] 2-Animal fibers (hair, silk, and wool) 2-Bacterial nanocellulose [32] 3-Plant fibers (lignocellulose) [33] 3-Nanocrystalline cellulose [34] 4-Nano-fibrillated cellulose [16]…”

“…Nanofibers were applied for plant protection through encapsulation of pesticides [56], including fungicides [66,67], herbicides [68], nano-silica grafted fiber [70], and smart nanotextiles for sustainable agriculture [13]. The use of nanofibrous filters in irrigation systems may involve functionalization (i.e., adsorption, filtration, and sterilization) by bioactive compounds, which could be achieved by interfacial polymerization, doping nanoparticles, self-assembly, and surface coating cross-linking or grafting, layer-by-layer [27]. Several nanomaterials such as graphene oxide could be used for water purification because of its multi-functionality, such as an antibacterial agent, excellent adsorption property, and photocatalytic abilities [77].…”

Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.

“…The agricultural sector is critical for delivering food, feed, fiber, and fuel, but it suffers from a variety of losses due to abiotic stress, pathogen infestation, and soil fertility reduction (Badgar et al, 2021). Nanotechnology has the ability to increase the efficiency and quality of agricultural output while potentially addressing prevalent issues (El-Shahawy et al, 2022).…”

HE SCIENTIFIC community has been more interested in nanomaterials based on graphene because of their distinctive chemical and physical characteristics. Recently, agricultural fields have routinely employed graphene oxide (GO). This study aims to produce graphene oxide using a modified Hummers method without sodium nitrate, using an environmentally friendly approach. The process involves the chemical oxidation of commercial graphite powder into graphene oxide using the modified Hummer's method. Also, the current study included the characterization of graphene oxide (GO) by X-ray diffraction (XRD), ultraviolet-visible spectrometer (UV-vis), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), atomic force microscopy (AFM), and elemental analysis (EA) were all used in the GO characterization. GO was evaluated using TEM images, which revealed that the GO sheets exhibited single and double lamellar layer structures with irregular forms and a thickness of 23 nm. The XRD patterns indicated that the GO peak centered at 2θ value 24º corresponds to an interplanar distance of carbon atoms arranged in (002) hexagonal layers; the interlayer spacing is approximately 8.61 Å according to the Scherrer equation. The oxygen-containing functional groups' presence in GO films like hydroxyl, carboxyl, epoxy, carbonyl, and C=C bunches was explained by a Fourier-change infrared spectrum analyzer (FT-IR) due to graphite oxidization in GO without twisting in the graphite layer structure. According to EA findings, the GO sheet's C element content was approximately 47.15 percent, O was 51.8%, H was less than 0.01%, and N was 1.02%. The UV-VIS spectrometer study revealed that the GO sheet exhibited an excellent optical reaction. The thickness and sidelong shape study of graphene oxide sheets by using atomic force microscopy (AFM). The SEM micrographs of GO obtained using modified Hummers handling demonstrate that the GO is made of two-dimensional sheets.
