“…The icing delay time of specimens from Series 2 was 328 s. However, the icing delay time of specimens with PDMS was lower than the times presented in the literature. Various types of coatings based on PMDS are characterized by icing delay times of 298 s at −10 °C [ 38 ], 600 s at −10 °C [ 39 ], 1472 s at −15 °C [ 40 ], 1800 s at −5 °C [ 41 ], 1380 s at −10 °C [ 41 ], 210 s at −15 °C [ 41 ], and 673 s from room temperature to −10 °C [ 42 ].…”

The aim of this study was to obtain a superhydrophobic coating by modifying anodized aluminum using polydimethylsiloxane (PDMS). In order to obtain a superhydrophobic coating on an aluminum substrate, a multistage treatment was implemented. Specimens of aluminum were treated by abrasive blasting, anodization in sulfuric acid, impregnation by PDMS, rinsing in toluene to remove excess of PDMS, and curing. A rough surface with an additional low free energy layer on it resulted in a superhydrophobic effect. The coating obtained has an average contact angle of 159°. The specimens were tested in terms of durability in natural conditions. Additionally, anti-icing and anti-fouling properties were evaluated. The coating was compared with anodized aluminum obtained by a basic process.

“…Finally, when large accumulations of snow and ice fall from structures there is a risk of both material damage and injuries. [1,2] Active heating [3,4] and anti-freezing fluids [5,6,7] are well-known traditional methods for ice removal, which are energy-intensive and could cause serious environmental pollution. [8,9] In the past years, many low ice adhesion strength coating materials have been developed, showing promising potential to solve the ice accumulation problem.…”

“…There are several reports on the preparation of self-healing antiicing materials, [11,20,24] which have higher ice adhesion strength (40-60 kPa) than present reports. [5,10,25] There are extrinsic self-healing and intrinsic self-healing materials, [26,27,28,29] respectively. The extrinsic self-healing materials achieve self-repairing properties through releasing the self-healing agent into crack interfaces.…”

Accumulation of snow and ice often causes problems and even dangerous situations for both industry and the general population. Passive de‐icing technologies, e.g., hydrophobic, liquid‐infused bionic surfaces, have attracted more and more attention compared with active de‐icing technologies, e.g., electric heating, hot air heating, due to the passive de‐icing technology's lower energy consumption and sustainability footprint. Using passive de‐icing coatings seems to be one of the most promising solutions. However, the previously reported de‐icing coatings suffer from high ice adhesion strength or short service life caused by wear. An intrinsic self‐healing material based on poly‐silicone‐urea is developed in this work to address these problems. The material is prepared by introducing dynamic disulfide bonds into the hard phase of the polymer. Experimental results indicate that this poly‐silicone‐urea has a self‐healing efficiency of close to 99%. More interestingly, it is found that the coating prepared from this poly‐silicone‐urea has a super low ice adhesion force, only 7 ± 1 kPa, which is almost the lowest value compared with previous intrinsic self‐healing de‐/anti‐icing reports. This material can maintain low ice adhesion strength after healing. This intrinsic self‐healing poly‐silicone‐urea can meet several practical applications, opening the door for future sustainable anti‐/de‐icing technologies.

Icephobic Performance of Combined Fluorine-Containing Composite Layers on Al-Mg-Mn–Si Alloy Surface

et al. 2021

This paper presents the results of an evaluation of anti-icing properties of samples obtained by plasma electrolytic oxidation (PEO) with a subsequent application of superdispersed polytetrafluoroethylene (SPTFE) and polyvinylidenefluoride (PVDF). A combined treatment of the samples with SPTFE and PVDF is also presented. It is revealed that impregnation of a PEO layer with fluoropolymer materials leads to a significant increase in surface relief uniformity. Combined PVDF–SPFTE layers with a ratio of PVDF to SPTFE of 1:4 reveal the best electrochemical characteristics, hydrophobicity and icephobic properties among all of the studied samples. It is shown that the decrease in corrosion current density Ic for PVDF–SPFTE coatings is higher by more than five orders of magnitude in comparison with uncoated aluminum alloy. The contact angle for PVDF–SPFTE coatings attain 160.5°, which allows us to classify the coating as superhydrophobic with promising anti-icing performance. A treatment of a PEO layer with PVDF–SPFTE leads to a decrease in ice adhesion strength by 22.1 times compared to an untreated PEO coating.
