Preparation of Degradable Superhydrophobic Mg/P/Z/F/H Composite Materials and Their Anticorrosion

Abstract

In this study, the degradable superhydrophobic Mg/P/Z/F/H (magnesium/poly(-caprolactone)/zinc oxide/1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES)/heating process) composite materials were prepared through dip-coating method and heating process, for enhancing the corrosion resistance of the AZ91D magnesium alloys. The electrochemical measurements revealed that the Mg/P/Z/F/H materials significantly improved the corrosion resistance of the magnesium alloys in 3.5 wt.% NaCl. The Mg/P/Z/F/H composite materials exhibited efficient self-cleaning properties, good adhesion strength, and stability in wet atmosphere.

Super‐liquid‐repellent thin film materials for low temperature latent heat thermal energy storage: A comprehensive review of materials for dip‐coating

“…They degrade into toxic and ecologically persistent molecules, such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Most literature on environmentally friendly STFs focused on inorganic-organic hybrid 185,219,[232][233][234][235][236][237][238] and organic 239 materials. The employed dip-coating process involved combining different surface texture fabrication strategies 174 and less environmentally damaging chemical materials.…”

“…The corrosive current measured after 6 h with surface defects was eventually inhibited and eliminated after 24 h. This was attributed to surface protection via surface physisorption and chemisorption of the inhibitor HMID in saline water. Xi et al 234 formulated an eco‐friendly composite which achieved superhydrophobicity with CAs of 159° to enhance the corrosion resistance of AZ91D magnesium alloys. The post‐heat treatment process after dip‐coating was done at 50°C for 30 min.…”

Overview of the challenges and current solutions in organic and hybrid coatings for historical monuments and architecture

“…These polymers have backbones with urethane bridges and free hydroxyl groups that resemble reacted epoxy products, making them more hydrophilic than typical polyurethanes. They have shown good adhesion and surface coating on glasses, metals, stone, and woods with hardness up to 5H and have taken advantage of many bio‐derived components 34,102–104 . Concrete coatings of which there are many commercial products have also been an area of focus for urethanes that have analogues to stone preservation 105 .…”

Enhancing high-temperature storage performance for the commercial lithium-ion battery via an effective additive strategy

“…It was found that adding graphene to the cathode can establish a reasonable lithium transport channel, thus improving the battery performance. 8 The coating layer modified the graphite electrode, 9 using polyacrylic acid (PAA), polymethacrylic acid (PMA), and polyvinyl alcohol (PVA), which could effectively inhibit the reaction between the electrolyte and graphite anode during storage, extending the battery storage life.…”
