“…The work [3] presents a detailed review of modern possibilities for creating and imparting hydrophobic properties to a surface. Accordind to the authors [4] the adhesion of ice to hydrophobic surfaces, which were obtained by depositing organosilicon and fluorine compounds on smooth and sandblasted aluminum alloy substrates.…”

Icing is a negative factor in the operation of various structures and equipment. Ice, due to its physical characteristics, has an aggressive effect on the surfaces of many materials. The use of anti-icing coatings is one of the ways to passively prevent the negative effects of icing. Anti-icing coatings developed by Technological Systems of Protective Coatings LLC (TSZP LLC) are promising coatings intended for operation in the aquatic environment. The authors studied the performance characteristics of the developed anti-icing thermal thermal coatings with a surface layer of PTFE under field testing conditions. The results of the experiments carried out confirmed the anti-icing properties of the coatings under study.

“…Обледенение аэродинамических поверхностей элементов конструкций авиационной техники: крыльев, лопастей воздушных винтов, воздухозаборников, обтекателей антенн, остеклений фонарей и датчиков пилотажно-навигационных приборов самолетов и вертолетов [1,2], лопастей ротора ветровых турбин [3,4] оказывает критическое влияние на их эксплуатационные характеристики, в частности: приводит к увеличению аэродинамического сопротивления, значительному снижению подъемной силы и падению скорости полета, ухудшению устойчивости и управляемости летательного аппарата, что обусловливает необходимость применения специальных гидрофобных материалов [5][6][7][8][9][10] и актуальность совершенствования противообледенительных систем и покрытий [11,12]. Физические аспекты процесса охлаждения и замерзания капель воды на поверхностях различных гидрофобных полимерных материалов исследованы в [13] с использованием видеозаписи в длинноволновом инфракрасном диапазоне.…”

A mathematical model was developed and a numerical modal analysis of the anti-icing mode of operation of the new indicator polymer coating with an integrated optical fiber piezoelectroluminescent (PEL) sensor for icing indication, location and self-cleaning from icing of aerodynamic surfaces was given. The fiber optic PEL-sensor is located in the plane of the coating. Receiver-analyzer of informative integral intensities of light signals is installed at output from optical fiber of sensor. Alternating voltage generator is connected to outputs of two control electrodes of sensor. The anti-icing function of the polymer coating is carried out automatically by thermo-mechanical actuation of the PEL-sensor on the appeared ice layer (on the ice crust of the coating) and only in those local areas of the coating where the thickness of the attached ice layer has reached a given critical value. Quality of cleaning from icing of surface of anti-icing coating is controlled by algorithms of digital processing of informative light signals at output from optical fiber of PEL-sensor. As a result, improved efficiency and control of de-icing on aerodynamic surfaces is achieved, especially for extended surfaces. The energy efficiency of the anti-icing polymer coating is increased due to the locality and self-control of the icing process. The modal analysis was carried out in an ANSYS finite element analysis package based on a numerical solution of the electrical-elasticity boundary value problem of stationary electromechanical oscillations of the representative cell of the anti-icing indicator polymer coating in the absence and presence of an ice layer of different thickness. Results of calculation of natural frequencies and forms of oscillations of representative cell of anti-icing coating, amplitude-frequency characteristics of mechanical stresses at coating/ice boundary for different values of thickness of attached ice layer for case of action of harmonic "force" in form of control electric voltage on electrodes of built-in PEL-sensor are presented.

“…In the work [2] conclusions were drawn that smooth surfaces based on elastomers and superhydrophobic coatings increase time of water droplet freezing and decrease ice adhesion. Such coatings supposed to be effective anti-icing coatings.…”

“…In this case, air is in the depressions of the relief. The wetting angle is determined by the Cassie -Baxter equation [7] cosθ′=-1+Φs(cosθ+1), (2) where Фs is the fraction of the surface area in contact with the surface of the drop. Therefore, superhydrophobic surfaces should have a small fraction of the surface area in contact with the surface of a water drop.…”

Information on the effect of organosilicon liquid on the hydrophobic properties of coatings, based on acrylic resin, is presented. It is shown that the value of the contact angle on the anti-icing coating is 151-154 degrees. When moistened for 72 hours, a decrease in the value of the contact angle, especially on the control coating, is 81-103 degrees. However, at the introduction of liquid 136-41, a decrease in the contact angle is insignificant. The surface energy of the coatings was calculated. It was found that the introduction of an organosilicon liquid in an acrylic composition increases the surface energy of the coatings.
