“…3d. The stretching vibration peaks located at 3300 cm -1 and 2900 cm -1 in RC are corresponding to -OH and -C-H of polysaccharide molecular skeleton (Kamtsikakis et al 2021). MdC-Op shows a more obvious peak at 1060 cm -1 , which is recognized as C-O-C generated by the etherification between CHPTAC and RC (Liu et al 2021).…”

Traditional dyeing process of cotton has caused a large amount of wastewater with high salt content, which seriously damages the ecological environment. In this work, cotton fabric was modified with 3-chloro-2-hydroxypropyl trimethyl ammonium chloride in order to decrease the electrostatic repulsion with the anionic dyes. A systematic optimization of the process has been performed. The acid dyes were applied instead of the common reactive dyes to dye the modified fabrics. The advantage of the high dye-uptake of acid dyes is studied. The levelness of the fabric dyed by reactive dyes and acid dyes were compared. The adsorption process and the bindings between the modified fabric and anionic acid dyes were further explored. The dyeing process were optimized. Finally, the dye-uptake of the modified fabric dyed by optimized conditions achieves to about 92%, which is comparable to traditional cotton dyeing process.

“…Kamtsikakis and group [ 117 ] fabricated a different CNC incorporated nanocomposite membrane and explored the ethanol-recovery pervaporation performance for the mixture sample of ethanol-water. The fabricated membrane with CNCs integration was based on a polystyrene-poly(butadiene)-poly(styrene) (SBS) matrix and was further decorated with oleic acid moieties (OLA-CNCs).…”

Membrane-based desalination has proved to be the best solution for solving the water shortage issues globally. Membranes are extremely beneficial in the effective recovery of clean water from contaminated water sources, however, the durability as well as the separation efficiency of the membranes are restricted by the type of membrane materials/additives used in the preparation processes. Nanocellulose is one of the most promising green materials for nanocomposite preparation due to its biodegradability, renewability, abundance, easy modification, and exceptional mechanical properties. This nanocellulose has been used in membrane development for desalination application in the recent past. The study discusses the application of membranes based on different nanocellulose forms such as cellulose nanocrystals, cellulose nanofibrils, and bacterial nanocellulose for water desalination applications such as nanofiltration, reverse osmosis, pervaporation, forward osmosis, and membrane distillation. From the analysis of studies, it was confirmed that the nanocellulose-based membranes are effective in the desalination application. The chemical modification of nanocellulose can definitely improve the surface affinity as well as the reactivity of membranes for the efficient separation of specific contaminants/ions.

“…The SE values of the textiles immersed in deionized water, NaCl and alkaline solutions are almost unchanged. The textile immersed in ethanol shows a decreased SE because the swelling of SBS leads to the separation of magnetic LM droplets inside the fibers . If immersed in acidic sweat and strong acid solution, the SE of the textiles decreases in the initial 48 h due to the corrosion of the magnetic LM on the fiber surface, and then the SE is relatively stable.…”

Stretchable conductive fibers are an important component of wearable electronic textiles, but often suffer from a decrease in conductivity upon stretching. The use of liquid metal (LM) droplets as conductive fillers in elastic fibers is a promising solution. However, there is an urgent need to develop effective strategies to achieve high adhesion of LM droplets to substrates and establish efficient electron transport paths between droplets. Here, we use large-sized MXene two-dimensional conductive materials to modify magnetic LM droplets and prepare MXene/magnetic LM/poly(styrene-butadiene-styrene) composite fibers (MLMS fibers). The MXene sheets decorated on the surface of magnetic LM droplets not only enhance the droplet adhesion to substrate but also bridge adjacent droplets to establish efficient conductive paths. MLMS fibers show several-fold improvements in tensile strength and elongation and a 30-fold increase in conductivity compared with pure LM-filled fibers. These conductive fibers can be easily woven into multifunctional textiles, which exhibit strong electromagnetic interference shielding and stable Joule heating performances even under large tensile deformation. In addition, other advantages of MLMS textiles, such as high gas/liquid permeability, strong chemical resistance (acid and alkaline conditions), high/low-temperature tolerance (−40–150 °C) and water washability, make them particularly suitable for wearable applications.
