“…On the contrary, some crystallization phenomena also bring negative effects on our daily life and industrial production such as the calcification of joints, gouts, and kidney stones as well as water scales . Because the underlying mechanism for scale problems also roots in crystallization, it is absolutely necessary to understand the crystallization behavior of inorganic salts on the surfaces, such as CaCO 3 , calcium sulfate (CaSO 4 ), and calcium phosphate (Ca 3 (PO 4 ) 2 ), greatly depending on the practical scenarios (e.g., thermal desalination and petroleum industry) . Generally, scale formation on these heat transfer surfaces can be classified into two different modes: “deposition mode” and “adhesion mode” ( Figure ) .…”

The energy problem has been a matter of some concern worldwide over the past 20 years. On the opposite side of energy production, energy loss is another crucial problem of current energy due to the low efficiency of heat transfer from scale deposition. However, less attention has been paid on the further development of advanced antiscaling interfacial materials, which may provide promising ways to save energy by reducing scale fouling. Herein, the development of antiscaling strategies is summarized from the basic theories and fabrication methods to antiscaling interfacial materials with potential applications. First, the mechanism of scale formation and the corresponding effect on thermal conductivity are introduced. Second, the typical fabrication approaches of antiscaling interfacial materials are briefly described. Finally, the performance, potential applications, future challenges, and opportunities of the advanced antiscaling interfacial materials are comprehensively discussed.

“…Many researches attest in particular the effectiveness of hydrophobic coatings on mitigation of crystallization fouling in heat exchangers [4][5][6][7]. Crystallization fouling is one of the most common types of fouling involving heat exchangers and consists in the precipitation and deposition of dissolved salts, after the supersaturation [8].…”

The technology of the organic/inorganic hybrid coating was employed in the preparation of a hydrophobic coating (contact angle higher than 140°) for fouling mitigation on stainless steel heat transfer surfaces. A commercial triethoxysilane perfluoropolyethers was combined with a sol-gel silica network with the aim to increase the mechanical and thermal resistance of the films when exposed to aggressive liquid environments as the heat exchanging fluids. The experimentation on a shell and tube heat exchanger pilot plant confirmed the ability of the hybrid coating to prolong the crystallization fouling induction period of 200 h in respect to an uncoated heat exchanger, operating in the same conditions. Moreover, the fouling particles deposited on the coated heat transfer surfaces had only slight adhesion strength toward the coated surfaces and were easily removed by inducing higher wall shear stresses inside the tubes of the plant.
