▎ 摘 要
NOVELTY - Graphene anti-corrosion and anti-fouling nano-material (I) is new. USE - (I) is useful: in substrate shielding barrier (substrate includes metal, preferably iron, copper, nickel, aluminum, gold, silver, magnesium and/or alloy), marine biological inhibition, marine heavy anti-corrosion, (marine organism includes bacteria, fungi, algae and/or Protozoa) and anti-fouling or thermally conductive coating fields (claimed); and as substrate for device. ADVANTAGE - (I): has corrosion resistance, solubility, and significant marine antifouling effect; and ensures significant innovative significance and practical value of engineering. DETAILED DESCRIPTION - Graphene anti-corrosion and anti-fouling nano-material of formula (I) is new. R1 and R2 = aromatic group, aliphatic chain group, alicyclic group (optionally substituted) or H; ubstituent = C, H, and heteroatom (number of substituent is 1-5); heteroatom = N, O, S or P; aromatic group = phenyl (optionally substituted) benzyl or phenethyl; aliphatic chain group = 1-16C aliphatic chain groups, preferably methyl, methylene, ethyl or propyl; and alicyclic group = 3-8C alicyclic group, preferably cyclopropane, cyclobutane or cyclopentane. INDEPENDENT CLAIMS are also included for: (1) preparation of (I); and (2) device, comprising a substrate, where the substrate is (I).
