    Abstract: Corrosion inhibition systems, including coated substrates, coating materials and corrosion inhibition compounds, and methods of making the same are disclosed. These systems and methods include corrosion inhibition compounds that are responsive to corrosion at a surface, releasing active inhibitor groups upon a corrosion stimulus. The active inhibitor groups are selected to block corrosion at the surface by inhibiting oxidation reactions, reduction reactions and/or by forming a passivation layer. Corrosion inhibition compounds may be linear polymers that include the inhibitor groups linked together with labile linkages that are disulfide or metal-sulfide bonds.

    Abstract: Aspects of the present disclosure provide a coating composition that includes a polymer material comprising an electrically conductive polymer; and a coated or partially coated magnetic material comprising a magnetic material and an antioxidant material. Aspects of the present disclosure further provide a method of making a coating composition that includes introducing, under first conditions, a magnetic material to a passivation solution comprising an antioxidant to form a coated (or partially coated) magnetic material; and introducing, under second conditions, the coated (or partially coated) magnetic material to a mixture comprising a polymer material to form a coating composition. Aspects of the present disclosure further provide a coated substrate that includes a film and a substrate, the film including a coating composition that includes an electrically conductive polymer, a magnetic material, and an antioxidant.

    Abstract: Described herein are static dissipating coatings and thermally-stable static-controlled (TSSC) electronic circuits, comprising such coatings. Also described herein are methods of forming such coatings and circuits. In some examples, a static dissipating coating comprises a conductive polymer and a thermally-stable base polymer. The conductive polymer comprises polyaniline and, in some examples, a conductive agent, such as dinonylnaphthalene sulfonic acid (DNNSA), dodecyl benzene sulfonic acid (DBSA), and/or camphor sulfonic acid (CSA). The thermally-stable base polymer comprises one or more copolymers of butyl-methacrylate, such as poly-butylmethacrylate-co-methyl methacrylate (PBM). The amount of the conductive polymer is specifically controlled to ensure the coating's overall conductivity and thermal stability. In some examples, the conductive polymer concentration is at or less than 25% by weight. The conductivity of the coating is between 10−9 S/cm and 10−6 S/cm even after being exposed to 150° C. for up to 24 hours.
