## Description

- description: "\r\nThe anticorrosion ability of ultrathin coatings with bio-inspired
    organic polymers is demonstrated. We prepared a series of catechol-containing
    poly(alkyl methacrylate)s by free radical polymerization. These copolymers were
    spin-coated on various corrosion susceptible metal/alloy substrates of magnesium,
    aluminum, copper and iron without any harsh pretreatment. Several key factors
    like molecular structure, composition ratio and processing conditions were wisely
    tailored to afford a transparent, firm and sub- micron polymer coating on those
    substrates. Corrosion resistance of the polymer-coated substrates was thoroughly
    investigated by immersion tests in salt-water and acidic solutions, polarization
    tests, and visual inspection. Formation of an anomalous dense layer of ca. 5 nm
    thickness adjacent to the metal surface and a remarkable effect of thermal treatment
    were clearly observed by neutron reflectivity measurements, leading to a highly
    protective ability against foreign molecules e.g. water or corrosive ions. A key
    molecular design for anticorrosive polymer coating was revealed to be a combination
    of strong and versatile binding ability of catechol units and defect free polymer
    layers formed on the metal substrates in the presence of hydrophobic alkyl chains."
