Fabrication of stable and versatile superhydrophobic PTFE coating by simple electrodeposition on metal surface

Fabrication of Nanostructured Corrosion-Resistant Superhydrophobic Coating on Copper by Electrodeposition: A Comprehensive Critical Review

“…27,[110][111][112] Drag reduction.-In fluid mechanics, drag is a form of visco force that opposes the motion of an object; air drag and hydro drag act on airplane ships, cars which decrease the effective efficiency of the machines and instruments; superhydrophobic coating can be used to minimize the drag, surface's nanostructure alter the roughness potentially that influence the air flow. 65,[113][114][115][116][117] Anti-fogging.-Fogging occurs when warm, moist air comes in contact with a colder surface, causing the vapor to condense into small droplets, resulting in foggy or hazy vision that may cause accidents and loss of life so superhydrophobic coating can help to migrate fog by repelling water droplet this coating can apply in eyewear, mirror camera windshields for anti-fogging and clear vision. 53,55,65,80,118 Anti-microbial coating.-Accumulation of bacteria is a major concern in a field that causes economic loss and even loos of life; anti-microbial coating reduces the accumulation of bacteria on a surface, and some coating can kill the bacterial according to the US Protection Agency, the copper surface can have anti-microbial properties and kill almost 99.98% in just 2 h but the mechanism how these coating are very complex.…”

[119][120][121][122][123] Anti-icing applications.-Working efficiently on ice is very difficult for instruments and machines, so it reduces the workability of instruments, which causes economic damage and affects human lives.…”

Recent advances in prevailing antifogging surfaces: structures, materials, durability, and beyond

“…Specific structures and parameters are important elements affecting surface wetting behavior and optical properties. The bottomup method mainly includes sol-gel (solution) coating, 83,84 LBL assembly, [85][86][87] chemical vapor deposition, [88][89][90][91] physical vapor deposition, and redox reaction, 92 which can be used to prepare antifogging coatings with patterned structures or rough surfaces on different substrate materials. In addition, there are some unconventional methods, such as casting, 36,93 sparking, 94 hot pressing, 95,96 and blow molding, 97 used to directly fabricate the antifogging surface.…”

Hydrovoltaic energy from water droplets: Device configurations, mechanisms, and applications

“…Four typical configurations are shown in Figure 6, including one fully covered bottom electrode (Figure 6a), one partially covered top electrode (Figure 6b), a combination of one partially covered top electrode and one fully covered bottom electrode (Figure 6c, referred to as the transistor-inspired structure), and two fully covered electrodes (Figure 6d, one is for the top electrode and the other is for the bottom electrode). Among these devices, PTFE is the most commonly used material for power conversion in droplets energy harvesting, due to its excellent superhydrophobicity, [97][98][99] electronegativity, 100 charge stability, 101,102 and so on.…”
