Graphene Established as Thinnest Anticorrosion Coating
Q Researchers with Vanderbilt University (Nash- ville, Tennessee) established that graphene, the thin- nest, strongest known material, is also the thinnest known coating for protecting metals against corro- sion, with a single layer of graphene providing the same corrosion protection as organic coatings that IZM UWZM \PIV Å^M \QUM[ \PQKSMZ +WXXMZ KWI\ML Ja a single layer of graphene grown through chemical vapor deposition corroded seven times slower than bare copper, and nickel coated by multiple layers of OZIXPMVM KWZZWLML
