Transparent superhydrophobic surfaces using a spray coating process

Spray coating of superhydrophobic and angle-independent coloured films.

Angle-independent coloured films with superhydrophobicity were fabricated from quasi-amorphous arrays of monodispersed fluorinated silica nanoparticles via one-step spray coating. The film exhibited a high contact angle (>150°) and a low roll-off angle (~2°) and the colour could be tuned to blue, green and moccasin by varying the size of the nanoparticles.

Fabrication and Performances of MTMS/TMCS Bilayer Transparent Superhydrophobic Silica Coating

The superhydrophobic silica coating has a great performance of self-cleaning which can be applied in the field of energy saving, anti-icing, drag reduction, etc. In this paper, Trimethyltrimethoxysilane (MTMS) /Trimethylchlorosilan (TMCS) superhydrophobic silica coating with two-layer structure was dip-coated. Atomic force microscope (AFM) images show that the surface morphology of MTMS/TMCS si...

Dropwise condensation heat transfer process optimisation on superhydrophobic surfaces using a multi-disciplinary approach

Dropwise condensation has superior heat transfer efficiency than filmwise condensation; however condensate evacuation from the surface still remains a significant technological challenge. The process of droplets jumping, against adhesive forces, from a solid surface upon coalescence has been studied using both experimental and Computational Fluid Dynamics (CFD) analysis. Both Lattice Boltzmann ...

One-step modification of superhydrophobic surfaces by a mussel-inspired polymer coating.

Mussels, which are promiscuous, underwater fouling organisms, attach to virtually any natural or synthetic organic/ inorganic substrate. The major components of mussels adhesive pads include proteins that contain the unusual amino acid 3,4-dihydroxy-l-phenylalanine (DOPA). In particular, Mytilus edulis foot protein-5 (Mefp-5), a protein located at a distal side of adhesive pads that attaches to...
