“…These materials are sources of cellulose, chitosan, sodium alginate, carrageenan, lignin, etc. These natural polymers have been exploited either directly after extraction or by mixing them in polymeric composites for more compactness and especially efficiency [310][311][312][313][314][315][316][317]. The adsorption results of various organic pollutants have been very promising in terms of their absorption capacity, simplicity of operation designs, cost-effective aspects, and reuse.…”

Academic research regarding polymeric materials has been of great interest. Likewise, polymer industries are considered as the most familiar petrochemical industries. Despite the valuable and continuous advancements in various polymeric material technologies over the last century, many varieties and advances related to the field of polymer science and engineering still promise a great potential for exciting new applications. Research, development, and industrial support have been the key factors behind the great progress in the field of polymer applications. This work provides insight into the recent energy applications of polymers, including energy storage and production. The study of polymeric materials in the field of enhanced oil recovery and water treatment technologies will be presented and evaluated. In addition, in this review, we wish to emphasize the great importance of various functional polymers as effective adsorbents of organic pollutants from industrial wastewater. Furthermore, recent advances in biomedical applications are reviewed and discussed.

“…Sodium alginate (SA) is a natural polysaccharide that is a by-product of iodine and mannitol extraction from the brown algae kelp or sargassum, which has promising biocompatible and biodegradable ( Mujtaba and Alotaibi, 2020 ). Studies have shown that CS forms a cross-linked structure with SA through electrostatic interaction and hydrogen bonding, which strengthens the linkage between the molecular chains of sodium alginate, thus enhancing the mechanical properties and release control ability of the hydrogel ( Kiti and Suwantong, 2020 ; Li et al, 2020 ; Kayan and Kayan, 2021 ).…”

This study aims to explore the feasibility of the novel temperature-sensitive hydrogel-based dual sustained-release system (Van/SBA-15/CS-GP-SA) in the repair and treatment of infectious jaw defects. Van/SBA-15 was prepared using the mesoporous silica (SBA-15) as a carrier for vancomycin hydrochloride (Van), and Van/SBA-15 was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectrometry (EDS), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET), and Barrett–Joyner–Halenda (BJH). The characterization results confirm that Van is loaded in SBA-15 successfully. Van/SBA-15/CS-GP-SA is constructed by encapsulating Van/SBA-15 in chitosan–sodium glycerophosphate–sodium alginate hydrogel (CS-GP-SA). The microstructures, sustained-release ability, biocompatibility, and antibacterial properties of Van/SBA-15/CS-GP-SA were systematically studied. Van/SBA-15/CS-GP-SA is found to have promising sustained-release ability, outstanding biocompatibility, and excellent antibacterial properties. This study provides new ideas for the management of infectious jaw defects.

“…[18][19][20] These environmental issues have led to the development of superabsorbents from natural polymers such as starch, 21 pectin, 22 chitin, chitosan, alginate, and lignin, among others. 23 Most of these are still produced as composites in combination with synthetic polymers, decreasing their biodegradability.…”

Carboxylated nanocellulose superabsorbent polymers (SAP) can be used to increase soil water retention in agriculture. The benefits investigated are influenced by the superabsorbent structure, composition and application rate.In this study, TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-oxidised nanocellulose superabsorbents were prepared using three different drying techniques: freeze-dried, and oven-dried at low and high temperatures. The swelling capacity in soil water extracts was measured and compared to deionised water. Soil was amended with different application rates of these superabsorbents to evaluate the effects on water retention, microbial community and their biodegradation.The absorption performance of nanocellulose superabsorbents is affected by the concentration and type of salts in the soil water extracts. Oven-dried at 50 °C SAP presents the highest ionic sensitivity attributed to its large number of accessible carboxylate groups. The water retention of the soil treatments increases with increasing application rate. Soil treated with the freeze-dried superabsorbent shows the highest water retention, whereas those amended with the 50°C oven-dried SAP remain moist the longest. The biodegradation rate of these materials depends on the application rate and nutrient availability. Carboxylated nanocellulose superabsorbents emerge as highperformance biodegradable materials for agricultural use, able to replace the current nonbiodegradable petrochemical-based superabsorbents. INTRODUCTIONWater is critical for agricultural production and food security. Irrigated agriculture uses about 70% of the water available for human consumption worldwide and accounts for 59% of the total fresh water in Australia (Organisation for Economic Co-operation and Development; Department of Agriculture 2020). Water availability has been impacted by climate change, drought and water shortage; its decrease has affected world agricultural development in recent years. According to Müller C. (2010), agricultural yields will decline between 2 -15% over the next 30 years due to climate change. Hence, the efficient use of water resources is crucial for the long-term sustainability of the agricultural industry.One strategy to optimise water retention in soils and hence making it more available to crops, is the use of superabsorbent polymers (SAPs) (Zohuriaan-Mehr et al. 2008). SAPs are three-dimensional (3D) networks of linear or branched hydrophilic polymers physically or chemically cross-linked (Guilherme et al. 2015). SAPs can absorb and hold water at hundreds of times their own weight and remain stable in their swollen state (Ahmed 2015;Ghorbani et al. 2019;Shen et al. 2016;Gross JR 1990). They have been extensively used in many applications including biomedicine (Curvello et al. 2019), food and beverages (Shewan and Stokes 2013), personal care and hygiene products (Bashari et al. 2018). In the agricultural and horticultural industries, SAPs have a range of applications which includes seed coatings, seed additives and root dips (Zoh...
