Rapid development of thickness‐controllable superamphiphobic coating on the inner wall of long narrow pipes

Abstract

A novel electrochemical technique had been introduced to prepare nanocrystalline superamphiphobic coatings inside of narrow pipes of significant length. The axially propagated ultrasound was utilized to ensure the scaling‐up potential of this technique. The coating had strong mechanical strength, durability in low/high pH solutions and the potential of controlling its thickness while preserving a stable nonwetting performance. In addition, the properties of anti‐scaling and drag reduction under the flowing circumstance had been demonstrated. © 2017 American Institute of Chemical Engineers AIChE J, 63: 3636–3641, 2017

Advanced Antiscaling Interfacial Materials toward Highly Efficient Heat Energy Transfer

“…In addition to water, the CAs of organic liquids (e.g., oil solutions) also exceeded 150°, which can be considered as superamphiphobic materials. By the combination of an ultrasound‐assisted electrodeposition (UED) and anodization, Wang and co‐workers also presented a superamphiphobic coating on the inner wall of copper pipe . After 7.2 × 10 3 s scaling test, the average coverage of CaCO 3 crystals on the bare and superamphiphobic surfaces were 46.80% and 6.27%, respectively (Figure C).…”

Sustainable scale resistance on a bioinspired synergistic microspine coating with a collectible liquid barrier

“…7,8 However, conventional scale-resistant strategies, such as mechanical descaling 9 and chemical detergents 10 often bring about plant shutdown and environmental pollution. Alternatively, superwettable surfaces 11 as functional coatings, such as superhydrophobic surfaces, [12][13][14][15][16][17][18][19][20][21][22] superhydrophilic surfaces 23 and liquid-infused surfaces, [24][25][26][27] have shown improved anti-scaling performance by mainly tuning the surface energy and surface morphology. In actual oil recovery and transportation, the produced water is often composed of complex multi-phases including oil products, water, salt ions and scales.…”

“…For example, the superhydrophobic PFSC-EDTA coating can improve scale resistance by 88.6% under static conditions. 21 Compared with them, [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][33][34][35][36][37][38] our BLOCK coating apparently surpasses the others in terms of scale-resistant performance and longevity (ca. 98% reduction vs stainless steel for 840 h).…”

Recent advances in the mechanical durability of superamphiphobic surfaces: A review

“…Durable superamphiphobic surfaces have been used to separate oil-water, 10,11 chemical shielding, 12 microfluidics (plasma nanotextures), 13 anti-drag, 14 patterned surfaces, 15 smart devices, 16 breathable protective wear, 17 etc. Lately, several other applications based on superamphiphobic surfaces, such as water harvesting, 18 moist air condensation, 19 oil and water transportation pipelines, 20 heat exchangers, 21 microchannels, 22 etc. have been reported.…”
