Scalable superhydrophobic coating with controllable wettability and investigations of its drag reduction

Fabrication of super-hydrophobic nickel film on copper substrate with improved corrosion inhibition by electrodeposition process

“…Recently, super-hydrophobic surfaces have aroused tremendous interest in academic research and potential applications in industry owing to their great importance, such as self-cleaning capability [1], drag reduction [2], water/oil separation [3], corrosion resistance [4] and so on. Generally, super-hydrophobic surfaces present a water contact angle (WCA) over 150° with the lotus effect (rolling angle (RA) below 10°) or the pinning effect (no RA or RA above 10°) [5][6].…”

From Extremely Water-Repellent Coatings to Passive Icing Protection—Principles, Limitations and Innovative Application Aspects

“…(see Figure 2), known in the scientific literature as superhydrophobic, superomniphobic or supernonwetting depending on the liquids involved [6][7][8][9][10], opens a broad range of potential practical relevance. It includes, but is not limited to self-cleaning surfaces [11][12][13], passive icephobic [14][15][16] and anti-bioadhesive coatings [17][18][19], systems for removal of oil contamination from water basins [20][21][22][23], anti-corrosive coatings [24][25][26], drag-reducing surfaces [27][28][29][30], pervaporation membranes [31,32], green engineering [33] or piezoresonance chemical and biological sensors [34][35][36][37][38].

New Manufacturing Process of Composites Reinforced with ZnO Nanoparticles Recycled from Alkaline Batteries

“…One way to enhance the hydrophobicity of these matrix surfaces is the introduction of dispersed ceramic nanoparticles, which increase its roughness. The application of different post-treatments can reduce the surface energy and contribute to create hierarchical micro and nanostructures [ 7 , 8 , 9 , 10 , 11 ]. In addition to providing hydrophobicity, the ceramic nanoreinforcements contribute with other improvements: increase in mechanical properties when there is an effective adhesion with the matrix, increase of thermal stability, enhancement of hardness, and wear resistance among others [ 5 , 12 , 13 , 14 , 15 , 16 ].…”
