“…Amylose consists of a linear glucose chain and is responsible for the amorphous structure in starch granules, representing 15–30% of their composition. In contrast, amylopectin is a branched glucose chain with crystalline zones and represents 70–85% of the starch [ 97 , 98 ].…”

Nanotechnology is a powerful tool for engineering functional materials that has the potential to transform textiles into high-performance, value-added products. In recent years, there has been considerable interest in the development of functional textiles using metal nanoparticles (MNPs). The incorporation of MNPs in textiles allows for the obtention of multifunctional properties, such as ultraviolet (UV) protection, self-cleaning, and electrical conductivity, as well as antimicrobial, antistatic, antiwrinkle, and flame retardant properties, without compromising the inherent characteristics of the textile. Environmental sustainability is also one of the main motivations in development and innovation in the textile industry. Thus, the synthesis of MNPs using ecofriendly sources, such as polysaccharides, is of high importance. The main functions of polysaccharides in these processes are the reduction and stabilization of MNPs, as well as the adhesion of MNPs onto fabrics. This review covers the major research attempts to obtain textiles with different functional properties using polysaccharides and MNPs. The main polysaccharides reported include chitosan, alginate, starch, cyclodextrins, and cellulose, with silver, zinc, copper, and titanium being the most explored MNPs. The potential applications of these functionalized textiles are also reported, and they include healthcare (wound dressing, drug release), protection (antimicrobial activity, UV protection, flame retardant), and environmental remediation (catalysts).

“…In addition to toxic dyes, polyaniline coated nickel oxide nanocomposite was also used successfully for elimination of phenolic compounds from water [24] . Fe 3 O 4 coated with polyaniline and polypyrrole magnetic nanocomposites were also used as adsorbents for the sequestration of 2, 4‐dichlorophenoxyacetic acid and found to be very effective [25] . However, pure Pan has not gained popularity for dye containing wastewater remediation because of deprived mechanical stability and poor dispersal capability in the solution.…”

In this research, polyaniline‐based magnesium ferrite nanocomposite (Pan−MgF−NC) was synthesized for the sequestration of cationic brilliant green (BG) dye. The Pan−MgF−NC revealed surface area of 56.19 m2/g and pore volume of 0.056 cc/g, with 20 to 40 nm of pore diameter. The impact of numerous parameters namely, solution pH, sorbent dose, dye initial concentration, and sonication time were explored and maximum dye abatement (90.28 %) was detected at solution pH of 8.0. The dominant mechanisms for the sequestration of BG onto Pan−MgF−NC were π‐π interactions, H‐bonding, and electrostatic attraction. The sorption kinetics of experimental data well fitted to pseudo second order analysis and Langmuir isotherm was the most consistent isotherm model with maximum uptake capability of 294.12 mg/g. Response surface methodology (RSM) was exhibited that the experimental BG removal (88.70 %) and model assimilated BG removal (89.13 %) are close to each other. Investigation related to scale‐up design also studied for large volume of industrial effluent. The laboratory scale fabrication cost of Pan−MgF−NC was found to be ∼85.00 USD/kg. The BG elimination efficacy with Pan−MgF−NC decreases from 90.13 % to 81.93 % after the fifth cycle, demonstrating the strong stability and reusability of Pan−MgF−NC.

“…Among naturally occurring polymers, starch is characterized by the greatest diversity of physicochemical properties, and is significantly influenced by the biodiversity of the raw materials from which it is obtained [ 1 , 2 , 3 , 4 , 5 ]. Although, for economic reasons, most of the starch produced in the world is derived from corn, wheat, and potatoes, in small amounts (less than 5% in total), it is obtained from other plant materials.…”

Aerogels are of increasing interest because of their exceptionally large surface area, porous structure, and low weight. Despite the significant increase in interest in the subject of starch-based aerogels, the number of detailed studies is rather scarce, which is especially evident in the case of chemically modified derivatives. Therefore, the study aims to evaluate the physicochemical properties of aerogels from chemically modified potato starch preparations (E 1422 and E 1450) obtained both from normal and waxy starches. Aerogels were prepared through the retrogradation of starch pastes followed by the gradual replacement of water with ethyl alcohol. The obtained preparations were characterized in terms of their bulk density, oil-binding capacity, as well as the texture and rheological properties of the formed pastes. Moreover, their usefulness was evaluated in an emulsion system employing rheological and low-field NMR methods. The obtained aerogels were characterized by a lower bulk density of 0.18–0.59 g/cm3 and 5.4–6.6 times higher oil-binding capacity compared to native potato starch. The chemical modification of starch helped to further alter the functional properties of the obtained aerogels, making them more effective oil binders, emulsifiers, and stabilizers (increasing the stability from 55 to 90%), which was especially evident for E 1450 preparation. Amylose content improved the aerogel properties, as waxy preparations were characterized by worse functional properties with the only exception of improved thickening ability. The most beneficial properties for the preparation of emulsions were observed for the aerogel obtained based on E 1450 normal potato starch.
