Case 1: Superhydrophobic Anti-icing Coating on 1060 Aluminum Alloy Mesh
Using a chemical microsculpting process, Alfa Chemistry created superhydrophobic 1060 aluminum alloy meshes. On the mesh substrate, a NaOH solution was employed to induce micron-level roughness. The surface energy of the mesh substrate was reduced using perfluoroalkyltrimethoxysilane (PFMS), which was mixed with the surface -OH to generate a nanocoating with superhydrophobicity. The water contact angle on the surface was 158°, whereas the oil contact angle was 163°. Not only does the created super double hydrophobic 1060 aluminum alloy mesh withstand corrosion and wear, but it also resists freezing.

Case 2: Polymeric guanidine derivatives for surface coating
The water-soluble feature might easily lead to antibacterial polymer polyhexamethyleneguanidine (PHMG) leaching from the coating system. As a result, converting PHMG to water-insoluble derivatives could be a viable option for preserving antibacterial characteristics.
Alfa Chemistry used a simple surface modification process to create an antimicrobial aluminum plate using water-insoluble PHMG-SS as a biocide. Strong electrostatic interactions were used to synthesis PHMG-SS, which was then implanted in the coating on the aluminum plate. The antimicrobial coating developed has hydrophilic characteristics, great UV resistance, and short-term jet fuel compatibility. Experiments have shown that its non-leaching qualities are beneficial.
