ABSTRACT:In this research, special wettable copper mesh owing superhydrophobicity and superoleophilicity property is reported using a low-cost, eco-friendly, rapid, and scalable synthesis methods. Hot water treatment (HWT) method is used to integrate the micro-textured copper mesh surface with a nanoscale roughness to achieve hierarchical micro-nano structured surface. The surface energy of the nanoscale In addition, the effect of the mesh's geometry on the wetting property was examined through correlations between wire diameter, pore size, and optimal values for the highest water CA.

“…Mechanical performances of functional coatings and their ageing attitude under severe exposure conditions, simulating for example some outdoor environments, represent an open issue for the current research [12][13][14][17][18][19][20], that needs to be deepened if innovative applications of these materials are foresight [49][50][51][52][53][54][55]. Overall, positive evidences -in terms of abrasion resistance and response to UV light exposure or sudden variations of climatic parameters (temperature/relative humidity) come out ( Table 4).…”

“…During the test the ice formation has been avoided all along the sample, some crystals have been occasionally observed, but easily detachable by a simple shaking. Static WCA detected after the test is practically unchanged, while CAH and SE -the key parameters to be controlled to design efficient icephobic surfaces [49,50,54] -are kept as low as 2°and 1.3 mN/m, respectively (Tables 4 and 5). …”

“…3,6 Recent studies also encourage the investigation of the effects of water repellent coatings that delay or even prevent ice from freezing to surfaces. [7][8][9][10][11][12][13] This effort intends to develop a proof-of-concept hybrid IPS that combines the principles of local heat addition by an efficient thermoelectric heater, to partition the ice shape, and mechanical deformation of the surface, to shed the residual ice. In addition, the section of the airfoil in which the residual ice is accreted consists of a surface with low ice adhesion properties that encourage ice shedding.…”

A key design factor impacting the utilization of electrical power to drive aircraft systems and subsystems is energy efficiency. With the design of an all-electric, hybrid ice protection system, energy consumption can be reduced to a large extent. The hybridization is achieved through an intentional partitioning of the ice at the stagnation line by melting via surface heating and ice shedding in the unheated regions of the airfoil surface via an electromechanical deicing system based on piezoelectric multilayer actuators. In addition, to reduce energy consumption, the adhesion forces between the ice and the airfoil surface can be reduced using an ultrasmooth, nanostructured surface with water and ice repellent properties that encourages ice shedding. Experimental investigations, performed in a laboratory-scale icing wind tunnel for a small-scale system configuration, reveal that the hybrid approach for ice protection reliably sheds the ice accreted on the airfoil surface. Compared to conventional state-of-the-art systems for ice protection, the hybrid approach is able to reduce power consumption up to 95 %. Beyond the laboratory tests, numerical simulations of the hybrid strategy analogous to the one used for the experiments are performed. The time history of the residual ice shapes aft of the heated region are simulated using the ice accretion prediction software LEWICE2D for a wet-running anti-icing subsystem. Finite element analyses of the effects of the piezoelectric actuators are then performed using Abaqus to investigate the ice shedding capability in the unheated regions of airfoil surface. It is shown that the variation in the thickness of the different ice shapes affects the stiffness of the model, and the ice shedding capability, respectively. Simulation results correlate well with experimental results obtained with the icing wind tunnel. It can be concluded that reliable operation of the hybrid system for ice shedding can be guaranteed when using a harmonic sweep excitation able to excite the structure at its resonance.
