Hydrophobic and superhydrophobic coatings for corrosion protection of steel
Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regul...
متن کاملPreparation of superhydrophobic surfaces on cotton textiles.
Superhydrophobic surfaces were fabricated by the complex coating of silica nanoparticles with functional groups onto cotton textiles to generate a dual-size surface roughness, followed by hydrophobization with stearic acid, 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane or their combination. The wettability and morphology of the as-fabricated surfaces were investigated by contact angle measuremen...
متن کاملSuperhydrophobic clothes: preparation and characterization
A superhydrophobic surface is coated on the surface of a cloth by MTCS (methyltrichlorosilane) nanoparticles and then, it is modified by SiO2–m–FTCS (1H,1H,2H,2H-Perfluorododecyltrichlorosilane) nanoparticles. This surface is characterized by SEM(scanning electron microscopy), and FT-IR (Fourier transform-infrared microscopy) and also its contact angle is investigated in various conditions and ...

متن کاملCoupling of surface energy with electric potential makes superhydrophobic surfaces corrosion-resistant.
We study the correlation of wetting properties and corrosion rates on hydrophobized cast iron. Samples of different surface roughnesses (abraded by sandpaper) are studied without coating and with two types of hydrophobic coatings (stearic acid and a liquid repelling spray). The contact angles and contact angle hysteresis are measured using a goniometer while corrosion rates are measured by a po...
