“…A shear stress can be applied to the interface so that the maximum shear strength at which the ice detaches is measured experimentally. Li et al [19,20] used this method to study the icephobicity of block copolymer coatings. A variation of this method was used by Fu et al [21], where a piston was used to shear off the ice from the sample surface.…”

“…However, the freezing front in a droplet can be observed by a change in opacity of the droplet. Water droplets are placed on supercooled test surfaces, and the time taken for a freezing front to appear is noted to quantify the icephobicity [19,61]. Eberle et al [10] showed that the delay in ice nucleation can constitute up to 25 h for a droplet at´21˝C if nanoscale roughness of the surface is carefully controlled.…”

“…It has been shown that at low humidity, fluorosilicone containing block copolymer can increase the delay in ice formation, as well as decrease the adhesion strength of ice on the surface [19,20]. Fluoroalkyl silane coating was seen to reduce ice adhesion compared to just hydrophobic nanoparticle coating [21].…”

Abstract:Tribology involves the study of friction, wear, lubrication, and adhesion, including biomimetic superhydrophobic and icephobic surfaces. The three aspects of icephobicity are the low ice adhesion, repulsion of incoming water droplets prior to freezing, and delayed frost formation. Although superhydrophobic surfaces are not always icephobic, the theoretical mechanisms behind icephobicity are similar to the entropically driven hydrophobic interactions. The growth of ice crystals in saturated vapor is partially governed by entropically driven diffusion of water molecules to definite locations similarly to hydrophobic interactions. The ice crystal formation can be compared to protein folding controlled by hydrophobic forces. Surface topography and surface energy can affect both the icephobicity and hydrophobicity. By controlling these properties, micro/nanostructured icephobic concrete was developed. The concrete showed ice adhesion strength one order of magnitude lower than regular concrete and could repel incoming water droplets at´5˝C. The icephobic performance of the concrete can be optimized by controlling the sand and polyvinyl alcohol fiber content.

“…Several studies on superhydrophobic surfaces and icephobicity may be found in the literature [172,173,[177][178][179][180][181][182][183][184][185][186][187][188][189][190][191][192], where ultimately these may lead to future solar cells able to avoid or minimize ice and snow formation on their surfaces.

Abstract:Building integrated photovoltaics (BIPV) offer an aesthetical, economical and technical solution to integrate solar cells harvesting solar radiation to produce electricity within the climate envelopes of buildings. Photovoltaic (PV) cells may be mounted above or onto the existing or traditional roofing or wall systems. However, BIPV systems replace the outer building envelope skin, i.e., the climate screen, hence serving simultanously as both a climate screen and a power source generating electricity. Thus, BIPV may provide savings in materials and labor, in addition to reducing the electricity costs. Hence, for the BIPV products, in addition to specific requirements put on the solar cell technology, it is of major importance to have satisfactory or strict requirements of rain tightness and durability, where building physical issues like e.g., heat and moisture transport in the building envelope also have to be considered and accounted for. This work, from both a technological and scientific point of view, summarizes briefly the current state-of-the-art of BIPV, including both BIPV foil, tiles, modules and solar cell glazing products, and addresses possible research pathways for BIPV in the years to come.

“…26,27 In the previous reports, we attempted to synthesize fluorosilicone block copolymers via free radical polymerization and reversible addition-fragmentation chain transfer (RAFT) polymerization. [28][29][30][31] The icephobicity results showed that the ice adhesion strength could be decreased on fluorosilicone block copolymer surfaces indeed, but the water droplets could not rebound from the surfaces and easily result in ice accumulation. It was reported that the rebound of a droplet Paper RSC Advances 2 | RSC Adv., 2015 This journal is © The Royal Society of Chemistry 2015 from a surface is related to the receding contact angle and can be achieved when the receding contact angle is higher than 100°.…”
