“…It is indicated that the HDPE substrates are prone to scaling. Existing studies have addressed that low surface energy substrate is effective to decrease fouling adhesion [ 25 , 41 , 42 ]. This study identifies that the surface free energy of the prepared composite is lower than that of the commercial HDPE pipe (shown in Table 4 ), indicating better scaling resistance.…”

“…Wang et al introduced super-amphiphobic coatings based on highly fluorinated and hierarchical-structure halloysite nanotubes (HNTs)/SiO 2 powder that could be applied as self-cleaning substrates [ 24 ]. Qian et al further added carbon nanofillers into fluorinated ethylene propylene and SiO 2 composites to improve their scale-inhibition properties by using a test of saturated CaCO 3 deposition [ 25 ].…”

Scaling commonly occurs at pipe wall during landfill leachate collection and transportation, which may give rise to pipe rupture, thus posing harm to public health and environment. To prevent scaling, this study prepared a low surface energy nanocomposite by incorporating silicone-acrylate polymer and hydrophobically modified nano-SiO2 into the high-density polyethylene (HDPE) substrate. Through the characterization of contact angle, scanning electron microscopy and thermogravimetry, the results showed that the prepared composite has low wettability and surface free energy, excellent thermal stability and acid-base resistance. In addition, the prepared composite was compared with the commercial HDPE pipe material regarding their performance on anti-scaling by using an immersion test that places their samples into a simulated landfill leachate. It was apparent that the prepared composite shows better scaling resistance. The study further expects to provide insight into pipe materials design and manufacture, thus to improve landfill leachate collection and transportation.

“…Under the synergism of topography and low surface energy, the superhydrophobic PPS/PTFE coating showed excellent antiscaling performance. Afterward, the carbon nanotubes were incorporated into the PVDF/fluorinated ethylene propylene/SiO 2 (PFS) composite coatings by spraying . The scaling rate on the superhydrophobic PFS-CNTs composite coating was only 44% of that on the hydrophobic PFS composite coating.…”

Recent Progress of Bioinspired Scalephobic Surfaces with Specific Barrier Layers

Bioinspired superwettable surfaces have been widely harnessed in diverse applications such as self-cleaning, oil/water separation, and liquid transport. So far, only a little work is focused on scalephobic capability of those superwettable surfaces. However, the troublesome scale deposition will inevitably be observed in our daily production and life, greatly reducing heat transfer efficiency and inhibiting the liquid transport. To address this annoying problem, as the emerging strategy, specific barrier layers are introduced onto superwettable surfaces to reduce or even avoid the direct contact between scale and the surfaces. In this feature article, we first provide the basic concept of bioinspired scalephobic surfaces with specific barrier layers. Then, we briefly introduce the typical fabrication methods of scalephobic surfaces. Later, we summarize recent progress of bioinspired scalephobic surfaces with specific barrier layers. Furthermore, we point out the guiding theory and criteria for the stability of barrier layers. Finally, we put forward the forecast on the existing problems and future direction in bioinspired scalephobic surfaces.
