Highly hydrophobic polyaniline nanoparticles for anti-corrosion epoxy coatings

Corrosion protection of aluminum alloy (AA2219-T6) using sulfonic acid-doped conducting polymer coatings

“…Corrosion resistant coatings are by far the most effective measure as they provide barrier protection and anodic protection. 8,[10][11][12] Among all the protective coatings, organic coatings are widely used due to their eco-friendliness, simple preparation process and better protection performance against aggressive external corrosion impact. Corrosive species from the environment penetrate the pores and cracks, thus accelerating coating failure with reduced protection performance.…”

Inverse Vulcanization with SiO2-Embedded Elemental Sulfur for Superhydrophobic, Anticorrosion, and Antibacterial Coatings

“…On the other hand, microorganisms dominated the degradation and/or failure of organic coatings of ship hulls and sea equipment in the ocean, limiting the effectivity of anticorrosion coatings in hostile marine environments. Circumventing the formation of biofilms on the coating of ship hulls and pipelines is also of extensive importance in the marine industry. − Meanwhile, the superhydrophobic surfaces are immersed in a polar solvent or a corrosive medium, and they may spontaneously form an air layer between the liquid–solid interface according to the anticorrosion mechanism . When the superhydrophobic surface adheres to some bacteria or microorganisms, these surfaces induce the water droplets to roll or rotate as the polar water droplets cannot be attached, eliminating the bacteria just landed or causing them to burst.…”

Boosting Cyclability and Rate Capability of SiOx via Dopamine Polymerization-Assisted Hybrid Graphene Coating for Advanced Lithium-Ion Batteries

“…To mitigate the challenges above, an effective strategy is to engineer its composite with conductive carbon or provide buffer structure toward the volume variation. − Park et al designed a porous SiO x with high specific surface area, which showed an initial charge capacity of 730 mA h·g –1 and a Columbic efficiency of 52% but a considerable capacity retention of 86.3% after 100 cycles . A unique watermelon-like structure of the SiO x –TiO 2 @C anode was engineered via the sol–gel method by Li et al, which performed an initial charge capacity and Columbic efficiency of 1011 mA h·g –1 and 63%, respectively.…”
