Electrostatic self-assembly cellulose nanofibers/MXene/nickel chains for highly stable and efficient seawater evaporation and purification

Self-Healable, Superhydrophobic, and Flexible Strain Sensor Based on Polyurethane Composite for Underwater Sensing

“…In this research, the SS-PU-1 electrostatic spinning fiber film is selected as the substrate of the sensor (hereinafter referred to as SS-PU). rGO, as the conductive element, is anchored at SS-PU by the driving effect of a strong ultrasonic wave; in addition, electrostatic self-assembly may occur between the rGO sheets . A layer of PDA is deposited on the rGO shell by the self-polymerization of dopamine in an alkaline environment .…”

Ultrathin and flexible polyimide/Ti3C2TX MXene composite films for electromagnetic interference shielding with harsh environment tolerance

“…The most common method for improving the mechanical properties of MXenes is to introduce a polymer matrix to compensate for their deficiencies through the excellent mechanical properties of the polymer itself. 32–40 Gogotsi et al 41 fabricated polyvinyl alcohol (PVA)/Ti 3 C 2 T X composite films with excellent mechanical properties by vacuum-assisted filtration. When the PVA content is 60%, the ultimate tensile strength and fracture strain are 91 ± 10 MPa and 4.0 ± 0.5% for the composite films, respectively, which are 4–5 times higher than those of the pure Ti 3 C 2 T X film.…”

Switchable NaCl cages via a MWCNTs/Ni[Fe(CN)6]2 nanocomposite for high performance desalination

“…[1][2][3] The amount of freshwater resources on land is very small, accounting for only 2.53% of the total global water. [4][5][6][7][8] The main forms of fresh water on land are glaciers and deep underground fresh water is difficult for humans to use, and the more accessible sources of fresh water (rivers, freshwater lakes and shallow groundwater) account for only 0.3% of global freshwater reserves; [9][10][11][12][13] therefore, there is a need to convert water resources that are not directly drinkable into fresh water resources that are directly drinkable by using indirect methods. [14][15][16][17] A number of desalination technologies have been developed, including multi-effect distillation, electrodialysis and reverse osmosis desalination technologies.…”
