Reducing ice adhesion by hierarchical micro-nano-pillars

The icephobic performance of alkyl-grafted aluminum surfaces

“…The design and use of surfaces/coatings with minimum ice adherence and reduced ice accumulation is still actively considered as the most appealing and universal approach to the problem [3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Most of the existing studies on anti-ice surfaces are focused on the reduction of ice adhesion strength [1,[5][6][7][8]10,[19][20][21][22][23][24] or delayed ice nucleation/formation [3,9,12,13,23,25,26]. Therefore lately the research in this area has been chiefly focused on the use and development of superhydrophobic surfaces (SHSs) for preventing ice formation and accumulation [4,[9][10][11][13][14][15][16][17][18][19]…”

Reducing ice accumulation and adhesion by using a flexible micro-rod film

“…Our previous study found that increasing micro-rod height (h) and decreasing micro-rod width (a) will make a surface more hydrophobic (He et al, 2013), and increasing surface hydrophobicity will decrease ice adhesion (He et al, 2014). Thus the micro-pillar size of the flexible film is selected based on the above design principle for better anti-icing properties, considering micro-fabrication conditions as well.…”

“…Given that roughness will increase the hydrophobicity of a hydrophobic material (Guo et al, 2011), rough textures are expected to be added on the PDMS surface to enhance hydrophobicity for better anti-icing properties. Our previous study showed that micro-rod texture, inspired from lotus leaf (Quere and Reyssat, 2008), on silicon surfaces have great influence on surface wettability (He et al, 2013) and an optimized design of micro-rod geometry could increase the surface hydrophobicity and reduce ice adhesion (He et al, 2014). It is, therefore, natural to propose using PMDS flexible microrod film as a solution for anti-icing flexible film.…”

An investigation of droplet bubble and liquid jet dynamics on superhydrophobic and hydrophobic surfaces

“…Bunlar gibi buz birikmesi istenmeyen yerlerde daha önceleri elektrikli ısıtıcı, sıcak hava ve buz önleyici sıvılar kullanılmıştır [4]. Süperhidrofobik yüzey kullanılarak yapılan buz önleme uygulamalarındaki öncül çalışmalar yüzeyin statik temas açısı dikkate alınarak yapılmıştır [13].…”
