Robust Self-Healing Graphene Oxide-Based Superhydrophobic Coatings for Efficient Corrosion Protection of Magnesium Alloys

ACS Applied Materials & Interfaces, Journal Year: 2022, Volume and Issue: 14(26), P. 30192 - 30204

Published: June 22, 2022

A self-healing coating possesses a broad application prospect in the metal corrosion protection area due to its pleasurable performance. By far, despite great deal of research studies that have been reported this field, it is still challenge construct an intrinsic surface can repair damaged structure and restore superhydrophobicity simultaneously. Herein, superhydrophobic was fabricated by combining polydopamine (PDA)-functionalized Cu2+-doped graphene oxide (GO), octadecylamine (ODA), polydimethylsiloxane (PDMS), which recover microstructure after chemical/physical damage. The as-prepared displayed excellent liquid repellency with water contact angle 158.2 ± 2° sliding 4 1°, endowed Mg alloy anticorrosion Once scratched, local will be automatically repaired through chelation catechol Cu2+. Also, rapidly restored under 1-sun irradiation even being etched O2 plasma. Furthermore, as-fabricated exhibited against magnesium immersion 3.5 wt % NaCl solution for 30 days, attributed efficient defects GO PDA π-π interactions inherent chemical inertia PDMS. Moreover, also favorable mechanical stability, durability, weather resistance. This study paves fresh insight into design robust coatings huge potential.

One-step fabrication of eco-friendly superhydrophobic fabrics for high-efficiency oil/water separation and oil spill cleanup

Nanoscale, Journal Year: 2021, Volume and Issue: 14(4), P. 1296 - 1309

Published: Dec. 22, 2021

The oily wastewater and oil spill caused by leakage accidents are extremely harmful to human health the environment. Thus, it is very important exploit superhydrophobic separation materials technologies for oil/water cleanup. In this study, using 1,4-conjugate addition reaction between polyethyleneimine (PEI) 3-(trimethoxysilyl)propyl acrylate (TMSPA), hydrolysis condensation of TMSPA dodecyltrimethoxysilane (DTMS) jointly connecting surface hydrophilic silica nanoparticles, hydrogen bond interaction residual amino group on PEI, covalently-crosslinked rough network structures were constructed fabric surfaces, which endow PEI/TMSPA/SiO2/DTMS fabrics with excellent properties. obtained not only showed heat resistance stability acid, alkali, salt organic solvents, but also good mechanical tape stripping washing tests. superhydrophobic, superoleophilic properties porous structure modified make have efficiency (98.49% after 18 cycles) cleanup (95.35% 9 cycles). This has characteristics simple preparation, environmental friendliness scale-up, makes a promising material actual

Bioinspired Nanofibrous Aerogel with Vertically Aligned Channels for Efficient Water Purification and Salt‐Rejecting Solar Desalination

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(23)

Published: March 8, 2023

Abstract Solar steam generation has become one of the most promising strategies to relieve freshwater crisis. Whereas, construction a solar‐thermal water evaporation structure that can operate continuously under sunlight generate clean with high efficiency, good stability, and salt‐rejecting capability is quite crucial but challengeable. Enlightened by transport transpiration process in trees, an advanced nanofibrous aerogel evaporator fabricated multifunctional capabilities through decoration functional component onto skeleton. The rational integration hierarchical constituents, results outstanding solar‐vapor conversion efficiency 96.1% fast rate about 2.33 kg m −2 h −1 1 sun. Additionally, exhibits remarkably outdoor highly effective salt‐resistant performances. Significantly, monitor salt precipitation its inner pores real time. This study demonstrates eco‐friendly economic solution for sustainable production using nanofiber aerogel‐based evaporators.
