Given complexity and diversity of oily wastewater, developing highly efficient separation materials through green and facile strategy are urgently needed. Herein, a smart strategy is demonstrated to transform raw cotton into uniform cellulose sponge for separation oil-in-water emulsion. The raw cotton is directly treated in zinc chloride aqueous solutions through a controllable dissolution process. After regeneration without any further chemical modification and freeze drying, the evolved cellulose sponge, which is composed of partially dissolved cotton fiber and exfoliated regenerated cellulose, exhibits interesting three-dimensional (3D) interconnected hierarchical porous network structure and stable wettability of superoleophobicity (θ oil > 150º) under water. Cellulose sponge has excellent underwater superoleophobicity and antifouling property due to the natural hydrophilicity of cellulose. Based on the beneficial 3D hierarchical structure and superwettability, the cellulose sponge can separate highly emulsified oil-in-water emulsions with efficiency up to 99.2% solely under the driving of gravity. Our strategy provides a generic way to convert cellulose-based materials into cellulose porous materials with excellent permeability, separation efficiency, antifouling, and reusability property for oil/water emulsions separation. This economical, environmentally friendly and functional cellulose sponge not only allows natural cotton resources to be used rationally with high value-added, but also effectively solves the problems of oily wastewater.

Cottonseed protein isolate (CPI) is a valuable agro-industrial waste with potential biotechnological applications. However, inadequate stability in water due to its characteristic hinders its widespread use. Therefore, a new sulfonation modification approach was developed to improve the amphiphilicity and structural flexibility of CPI. Structural characterizations confirmed the successful incorporation of sulfonate groups with structural and conformational changes. This significantly unfolded molecular-chain, and improved amphiphilicity, flexibility, and surface-hydrophobicity while reducing pI (5.1–1.7), and molecular-weight (5745–2089 g/mol). The modified samples exhibited improved emulsification with higher amounts of absorbed proteins on the droplet interface, smaller droplet size, and a higher zeta-potential. Additionally, they possessed good emulsification ability under acidic conditions. The nano-emulsions exhibited long-term stability (≥70 days) under different environmental conditions, with excellent fluidity. This study contributes to understanding sulfonation as a viable approach for improving protein properties, thus, opening up new possibilities for their application and maximizing their economic benefits.

Multi-ion fabrics (especially silver ion fabrics) have special advantages as electromagnetic radiation, but the use of noble metals enhances its cost. Electroless nickel plating (EP-Ni) has great potential application in fabricating low-cost metallized material. Here, EP-Ni on pure cotton surface to fabricate radiation protection suits for pregnant woman was established to replace traditional protection suits with silver film. The active groups on the cotton/polyester blend fiber surface could absorb tin and palladium ions, acting as catalytic centers, which can catalyze the reduction of Ni2+ in the plating solution. Ni particle with (111) crystal plane preferential oriented crystal structure deposited on cotton surface with a coarse microstructure. The Ni deposited amount is about 19%. The fabricated material exhibited a shielding effectiveness of 29.5 dB. Studies also shown that bending has no negative effect on crystallinity and electrical property. But more bending times could lead to crack, which would decline electromagnetic shielding performance by 24%.

Considering that the electromagnetic interference (EMI) shielding textiles are deeply affected by the accidental fires, we have designed an eco-friendly flame retardant and EMI shielding cotton fabric. Herein, the cotton fabric, a biomass material, serve as the skeleton and the polyethylenimine/phytic acid (PEI/PA) layer as well as silver nanowires (AgNWs) conductive networks are formed on the surface of cotton fibers through layer-by-layer assembled technology and dip-coating method, which is due to the strong electrostatic interaction and hydrogen bonding effect. The biomass material PA together with PEI functions well to be an effective intumescent flame retardant coating. Besides, the increasing amount of AgNWs constitutes an effective conductive metal shielding layer. Particularly, the cotton fabric with 24.2 wt% of PEI/PA layer and 7.5 wt% of AgNWs network possesses the effective self-extinguishing effect and minimizes the PHRR value about 58.59% of pure cotton fabric. Moreover, a high electrical conductivity of 2416.46 S/m and an impressive EMI shielding effectiveness of 32.98 dB are also achieved over the X-band frequency range with an absorption-dominated mechanism. The excellent flame retardant property and outstanding EMI shielding performance are attributed to the external well-constructed flame retardant layer and interconnected conductive network, which is confirmed by SEM images and EDS mapping images. Besides, it also keeps highly reliable shielding ability during the bending test, washing test and sandpaper abrasion test. Therefore, this flexible flame-retardant EMI shielding textile will benefit the eco-friendly and facile large-scale fabrication of multifunctional textile.

The ferric ions sludge produced during pollutants degradation was an obstacle for large scale application of Fenton oxidation technology. Herein, we reported a facile method using 2,2,6,6-tetramethylpiperidine-1-oxygen radical (TEMPO)-oxidized cotton fabric as a substrate for anchoring Fe(II) ions to produce Fe(II)-anchored cotton fabric. The formation of Fe(II)-anchored cotton fabric was confirmed using EDS analysis and FTIR measurement. Bath experiments indicated that Fe(II)-anchored cotton fabric could Fenton oxidize rhodamine B (RhB) dye in a high efficient rate (95.9 %) within 60 min without second pollution. Fe(II)-anchored cotton could be reused without any physical/chemical treatment and its decolorization efficiency was retained at 89.9 % even after the third cycle. Moreover, the decolorization behavior of Fe(II)-anchored cotton fabric for the RhB solution was affected by H 2 O 2 dosage, Fe(II) ion content, and inorganic salts. Kinetic study indicated that the RhB decolorization process fits a pseudo-first order well and the sorption isotherm assessment revealed that the reactive sorption of RhB dye on Fe(II)-anchored cotton fabric fits the Freundlich model.

This paper uses the scaleable and commercial in-situ (exhaust) dyeing method to fabricate reduced graphene oxide (rGO)/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) hybrids on knitted cotton fabrics to develop lightweight, flexible, and metal-free knitted cotton fabric for electromagnetic interference shielding (EMI SE) application. The graphene oxide (GO) and PEDOT: PSS solution were directly dyed and reduced through a green reducing agent C 6 H 8 O 6 (L-ascorbic acid) at a low temperature (60 °C) by a commercially used exhaust dyeing process on cotton fabric. The morphology and elemental analysis, mechanical stability, hydrophobicity, electrical conductivity, and (EMI SE) performance rGO/PEDOT: PSS dyed fabric has been systematically studied. The electrical conductivity of the resultant composite fabric significantly improved up to 4.2 × 10 3 Scm −1 due to the higher inter bonding and adhesion of fibers in the yarn, and fabric assembly, with each fiber surface finely coated with composite of rGO and PEDOT: PSS with each other due to less interlayer spacing. The mechanical stability of tensile strength and hydrophobic performance of rGO/PEDOT:PSS composite dyed hybrid (RPD-1) significantly improved up to 49 MPa and 156°, respectively, due to an increase of graphene wt.%. The resultant cotton fabric exhibited outstanding EMI shielding performance up to − 49 dB on 30–1530 MHz and 39 dB on 8–18 GHz (X-band) frequency range which shielded almost 99.99% of incident electromagnetic radiation waves.

A cotton fabric with special wettability was prepared in two simple steps. The surface of the fabric was grafted with silicon-oxygen group using 3-(methacryloyloxy) propyl trimethoxysilane (MSPMA) as the reagent, and then (3-mercaptopropyl)triethoxysilane (MPTES) was used to react with the grafted fabric under ultraviolet light according to the principle of thiolene reaction. Meanwhile, the modified cotton fabrics with various pore sizes were obtained via modifying the cotton fabric with different pore size under the same experimental conditions. The as-prepared fabric had a better hydrophobic and lipophilic effect, whose water contact angle could be up to 146.7° and the separation efficiency for different kinds of oil/water mixtures was better than 94%. In addition, the pore sizes of cotton fabrics had a great effect on the rate of oil/water separation, which increased with the increase of the pore size.

Water evaporation using photothermal materials is a cost-effective and sustainable technology for alleviating the world’s freshwater crisis, but oil contaminants and organic pollutants exist in the original water sources, which severely degrade the evaporation performance and pose environmental hazards. In this paper, we demonstrate a photothermal material (multifunctional cotton) that simultaneously demonstrates oil-resistance, organic pollutant removal, and a high water evaporation rate. A Schottky heterostructure was formed between polyaniline (PANI) and Ag NPs, which improved the photothermal conversion and achieved a water evaporation rate of 1.37 kg m −2 h −1 and photothermal conversion efficiency of 84.7% under one-sun illumination (1 kW m −2 ). Notably, various organic pollutants in the water source were thoroughly removed by visible-light catalytic degradation and adsorption, which displayed efficiencies of 99.3% and 97%, respectively. The multifunctional cotton also possessed excellent superoleophobicity, and repelled oil contaminants and organic pollutants in water. Considering these merits, the as-prepared multifunctional cotton is an outstanding candidate for water evaporation from various sources.

Dye/polymer nanosphere is a novel kind of colorant that can significantly enhance the dye utilization efficiency on textile. In order to improve the coloration ability of colored nanospheres, disperse dye/P(St-MAA) nanospheres with rough surface were successfully prepared through alkali pretreatment at pH 12 and coloration of disperse dyes. TEM image and particle size analysis indicate that the colored nanospheres had rough surfaces with the average particle size of 158.1 nm. The dye content of colored rough nanospheres was 63.7 mg/g, higher than the un-alkali-treated ones. The reason for the change of morphology, particle size and dye content was due to the swelling of nanospheres at alkali condition. The XRD , TGA and DSC diagrams show that the disperse dye molecules formed strong interaction with the macromolecular chains and aggregated to form crystals in the rough nanospheres. The printed cotton fabric shows higher color performance using the colored rough nanospheres because of the lower visible light reflectance. The printed fabric also exhibits satisfactory color fastness for practical application.

Microbial contamination on cotton textiles (CT) negatively affects people's health as well as the textile itself during use and storage. Using antimicrobial CT in a body-safe manner is currently still a challenge because it is difficult to balance killing microbes and protecting skin flora. Herein, a borneol-decorated CT (BDCT) through coupling of borneol 4-formylbenzoate molecules onto the amino-modified CT is reported. This BDCT shows strong and broad-spectrum microbially antiadhesive activities against gram-positive bacteria ( Staphylococcus aureus and S. epidermidis ), gram-negative bacteria ( Escherichia coli and Pseudomonas aeruginosa ), and fungi ( Aspergillus niger , Mucor racemosus , and Candida albicans ). Because of its unique stereochemical microbial antiadhesion mechanism, BDCT is harmless to skin flora. In addition, BDCT exhibits prominent durability of microbially antiadhesive capability by bearing 50 times of accelerated laundering. Therefore, this stereochemical BDCT strategy shows great potential for applications in the new generation of textiles, food packaging, and medical protection.

and can be restored to its original state after bending for 180° without obvious cracks. After 20 cycles continuous compression, the total unrecoverable strain loss is only 20% under strain of 60%. The composite also shows very prominent hydrophobicity, and the contact angle with water
reaches 145 degrees. It has strong adsorption capacity for organic reagents and oil, with adsorption ratios of 500% and 600%, respectively. In addition, the composite has a low thermal conductivity of 0.038 W/(m·K) at room temperature. The obtained composite exhibits considerable promise
in oil-water separation and thermal insulation.
