Fabrication of robust superhydrophobic microcapsule-based composite coating with self-healing and anti-scaling properties

Light‐Responsive Metal–Organic Framework (MOF)‐Based Liquid‐Like Coating for Sustainable Scale Resistance

“…a) Variation of added weight and fraction of scale coverage for MPL coatings after 96 h of CaCO 3 scaling experiments; b) Optical images showing scaling behaviors of different MPL coatings in saturated CaCO 3 solution after 24 and 96 h of solution evaporation; c) Comparison of scale added weight of MPL‐40 and the uncoated surface after different scaling periods; d) Comparison of the anti‐scaling performance of MPL‐40 and literature‐reported coatings, where Refs. [9,20,33,34] reported the increase of CaSO 4 and CaCO 3 scale weight on coatings, respectively. (Detailed conditions are listed in Table S3, Supporting Information); e) Scaling behaviors of MOF/LPDMS‐40 (ML‐40) and PL‐40 coatings in saturated CaCO 3 solution; f) The effect of irradiation on the anti‐scaling performance of the MPL‐40 coating (Note that “MPL‐40 (non UV)” refers to avoiding exposure to UV environment, and “MPL‐40 (non Vis)” denotes MPL‐40 that was exposed to UV environment while avoiding periodic visible light exposure).…”

“…Furthermore, in comparison with existing literature in the field of anti‐scaling, the anti‐scaling properties of the MPL‐40 coating continue to demonstrate significant advantages. [ 9,20,33,34 ]…”

“…[ 19 ] In contrast, fluorocarbon coatings provide a more durable solution, which prevents scale formation through increasing the nucleation energy barrier owing to their extremely low surface energy. [ 20 ] Very recently, liquid‐like surfaces have emerged as a new class of anti‐scaling coatings. Such coatings feature highly mobile polymer brushes with a glass transition temperature far below room temperature, which reduce the effective affinity interaction between the substrate and scale and exhibits even better anti‐scaling capability than the conventional fluorocarbon counterpart.…”
