“…Therefore, it is conducive to maintaining water droplet at the Cassie–Baxter metastable state during the MD process, preventing membrane fouling and wetting. The methods, including self-assembly, surface grafting, chemical vapor deposition, electrospinning, , plasma treatment, , photoetching, and other methods, , have been used to construct superhydrophobic structures on the membrane. The classical material for preparing superhydrophobic membranes is to use nanomaterials, such as SiO 2 , TiO 2 , and ZnO, to design micro-/nanostructures on the pristine membrane surface, followed by surface energy reduction.…”

Membrane distillation (MD)-based seawater desalination has garnered increasing attention in recent years because of its insensitivity to salinity. However, it was limited by salt scaling and membrane wetting due to the complexity of water environments. Herein, an alkali-activated poly(tetrafluoroethylene) (PTFE) membrane surface was functionalized using polydopamine (PDA) via in situ polymerization of dopamine at the air−water interface. Silver nanoparticles (Ag NPs) were further deposited onto the modified PTFE membrane surface by the reduction of silver ions. A superhydrophobic surface with micro-/nanostructures and ultralow surface energy was obtained after continuing to modify with 1H,1H,2H,2Hperfluorodecanethiol. The water contact angle of the superhydrophobic membrane can reach 153.2°. In direct contact MD tests, the superhydrophobic membrane exhibited a stable permeation flux (19.75 kg•m −2 • h −1 ) and excellent salt rejection compared with pure PTFE membrane. Additionally, the superhydrophobic membrane exhibited outstanding antiscaling and antiwetting properties, which considerably extended its service life. Therefore, it can be used as a reference to address salt scaling on the membrane surface.

The primary objective of this study was to demonstrate the effect of a phosphorus–copper complex on the flammability of polyamide 6 (PA6) materials, including organoclay-reinforced nanocomposites. The secondary objective was to compare the effectiveness of the deposition methods of the three-layer copper complex. Our previous work successfully revealed the effectiveness of reducing the flammability of polyamide composites by depositing phosphorus and copper compounds using a Layer-by-Layer technique. In the current work, we turned our attention to modifying the PA6 surface by electro-spray (ES) using the same flame retardants as before, and we investigated the effectiveness of the resulting surface protection against high temperatures during combustion. Surface roughness analysis revealed that the use of the ES method favors the formation of surface unevenness. The UL-94 test results showed that composite materials having 5-15 triple layers were among the best flammability classes compared to the others. Both types of materials tested also showed a tendency to reduce the heat release rate (HRR) by increasing the degree of surface coverage when using the electro-spray technique. Remarkably, deposition of 15 triple layers on the surface of the nanocomposite reduced the maximum HRR point by 20%. Graphical abstract
