“…In another study, Shahi et al [276] demonstrated the possibility of producing a biocomposite film (PVA-RC) based on regenerated cellulose fibers isolated from black oat and PVA (polyvinyl alcohol). It has been demonstrated that regenerated oat cellulose fibers are well dispersed in the polymer mixture and demonstrate good PVA/nanocellulose compatibility due to the formation of hydrogen bonds.…”

The current trends in environment protection and sustainable development demand the investigations in the field of searching new perspective sources for any production. Oat husks seems to be a perspective resource. Cellulose isolated from oat wastes can be used for the production of different materials such as hydro and aerogels, bacterial, nanocrystal and nanofibrillated cellulose, cellulose based composites and ethers. All these materials can be spent in different industries: production of pharmaceuticals, medicine (including targeted delivery of drugs, sponges etc.), agriculture (controlled delivery of pesticides or fertilizers), electronics, production of films, membranes, plastics, coatings, paints, biodegradable packages. In this review, we will demonstrate prospects for using oat husks to obtain cellulose and for obtaining materials based on the main oat husk polysaccharide. This review will evaluate the main achievements in this area. The analysis will allow a reader to form an analytical opinion about the prospects for using oat husks as a source for obtaining valuable products.

“…It is notable that the water uptake properties of the PVA-3, which was approximately 89% as indicated in Table 2, were superior compared to the published studies. The percentage of water uptake, also known as the swelling ratio, 44 of PVA/ regenerated cellulose film produced by Shahi et al was between 35 to 40% after being immersed in water for 24 h. PVA/ banana pseudostem fiber (BPF) film produced by Srivastava et al 45 exhibited 67.4% swelling. The high-water update in this study was due to the use of starch, which can hold water via hydrogen bonding.…”

Hydrodegradable material as the replacement for plastic could be a better option than biodegradable material due to its solubility in water, which could extend the landfill’s lifespan. On the other hand, biodegradable material requires tightly controlled waste management and proper facilities for degradation purposes. The starch film is highly soluble in water, exhibiting poor mechanical strength. This study aims to improve the strength of starch film by adding cellulose, which was isolated from rice husk and polyvinyl alcohol (PVA). Results showed that Type 1 – cellulose was extracted from rice husk. With the addition of PVA to the starch/cellulose film, the homogeneity of the mixture improved, as illustrated in FESEM images. The mechanical strength of film also greatly improved from 2 MPa to 4.2 MPa when 3 g of PVA was used. The film showed the sign of degradation after being immersed in water for 24 h due to its high-water uptake property (∼89%). This starch/cellulose/starch film could be used as an edible wrap and single-use material for varied applications such as disposable plates.

“…The ability of cellulose to immobilize dyes also exhibits a uniform dyes’ distribution on the RC film for high detection of heavy metal ions that are present in the irrigation water source [ 174 ]. Other than being an immobilization particle for the dyes employed in chemical sensors, cellulose is often being reinforced by other biodegradable synthetic polymers such as polyvinyl alcohol (PVA) to form flexible sensor film because of massive amorphous region of cellulose have aided in enhancing mechanical strength and optical transparency [ 186 ]. The humidity level of soil or moisture of the soil is a pivotal parameter to be monitored to yield quality crops.…”

Cellulose is one of the most abundant natural polymers with excellent biocompatibility, non-toxicity, flexibility, and renewable source. Regenerated cellulose (RC) products result from the dissolution-regeneration process risen from solvent and anti-solvent reagents, respectively. The regeneration process changes the cellulose chain conformation from cellulose I to cellulose II, leads the structure to have more amorphous regions with improved crystallinity, and inclines towards extensive modification on the RC products such as hydrogel, aerogel, cryogel, xerogel, fibers, membrane, and thin film. Recently, RC products are accentuated to be used in the agriculture field to develop future sustainable agriculture as alternatives to conventional agriculture systems. However, different solvent types and production techniques have great influences on the end properties of RC products. Besides, the fabrication of RC products from solely RC lacks excellent mechanical characteristics. Thus, the flexibility of RC has allowed it to be homogenously blended with other materials to enhance the final products’ properties. This review will summarize the properties and preparation of potential RC-based products that reflect its application to replace soil the plantation medium, govern the release of the fertilizer, provide protection on crops and act as biosensors.
