Scientists studied ultra-hydrophobic organic and inorganic clay nanocomposomes for epoxy coatings.
using hydrophobic silver and iron oxide nanoparticles, a new type of peeling super-hydrophobic nanocomposome based on hydrophobic soil loss (HMT) modified. The modified HMT nanocomposive material is mixed with epoxy resin, cured with polyamine hardeners, and easily sprayed on rough steel surfaces with a simple and effective one-step
.
HMT, which is mixed with the epoxy coating substation, has a maximum seawater contact angle of more than 150 degrees. Atomic force microscopes and scanning electron microscope images illustrate the peeling of HMTs and the production of rough surface coatings responsible for ultra-hydrophobic layered microstructures of iron oxide/HMT epoxy coatings. In addition, the porosity and reunification of Ag/HMT epoxy composites are the cause of their ultra-hydrophobic failure.
Ultra-hydrophobic epoxy nanocomposates
Ultra-hydrophobic epoxy nanocomposates have extraordinary adhesion, mechanical, chemical and wear resistance through salt spray resistance in high-salt seawater environments.
the study was published in March 2020 in volume 140 of Organic Coatings Progress.
