Title: Extraordinary Corrosion Protection from Polymer–Clay Nanobrick Wall Thin Films

Abstract

Metals across all industries demand anticorrosion surface treatments and drive a continual need for high-performing and low-cost coatings. Here we demonstrate polymer–clay nanocomposite thin films as a new class of transparent conformal barrier coatings for protection in corrosive atmospheres. Films assembled via layer-by-layer deposition, as thin as 90 nm, are shown to reduce copper corrosion rates by >1000× in an aggressive H₂S atmosphere. Furthermore, these multilayer nanobrick wall coatings hold promise as high-performing anticorrosion treatment alternatives to costlier, more toxic, and less scalable thin films, such as graphene, hexavalent chromium, or atomic-layer-deposited metal oxides.

Nanocomposite conformal corrosion barrier coating

Patent Schindelholz, Eric John ; Spoerke, Erik David ; Sorensen, Neil R. ; ...

Metals across all industries demand anti-corrosion surface treatments and drive a continual need for high-performing and low-cost coatings. Ordered thin films comprising aligned inorganic platelets dispersed in a polyelectrolyte polymer matrix provide a new class of transparent conformal barrier coatings for protection in corrosive atmospheres. For example, films assembled via layer-by-layer deposition, as thin as 90 nm, are shown to reduce copper corrosion rates by >1000× in an aggressive H₂S atmosphere. These coatings can provide high-performing anti-corrosion treatment alternatives to costlier, more toxic, and less scalable thin films, such as graphene, hexavalent chromium, or atomic layer deposited metal oxides.

Nanoscale thin film corrosion barriers enabled by multilayer polymer clay nanocomposites

Journal Article Percival, Stephen J. ; Melia, Michael Anthony ; Alexander, Christopher L. ; ... - Surface and Coatings Technology

In this paper, we describe the immersion corrosion resistance of multilayer polymer-clay nanocomposite (PCN) barrier thin films coated on low carbon steel. Deposited using a Layer-by-Layer (LbL) self-assembly process and only a few hundred nanometers thick, the thin film polymer clay nanocomposites (PCN) exhibited excellent corrosion barrier properties, comparable to coatings that are orders of magnitude thicker. PCN barrier thin films comprising up to 60 “bilayers” of polyethyleneimine and exfoliated montmorillonite were coated onto steel coupons and immersed in high salinity water for up to 7 days to evaluate barrier film corrosion resistance. PCN film performance is shown to bemore »« less

Influence of Clay size on corrosion protection by Clay nanocomposite thin films

Journal Article Melia, Michael A. ; Percival, Stephen J. ; Qin, Shuang ; ... - Progress in Organic Coatings

In this work, the influence of clay platelet size on the corrosion barrier performance of highly-aligned polymer clay nanocomposite (PCN) thin films was examined. Layer-by-layer (LbL) deposition of alternating branched polyethylenimine (PEI) and either laponite (LAP), montromorillonite (MMT) or vermiculite (VMT) clay platelets were assembled on mild steel plates to obtain 20 bilayer (BL) films and cross-linked using glutaraldehyde after deposition. The clay platelets were chosen based on their aspect ratio, approximately 30:1, 400:1, and 2000:1, respectively. Electrochemical impedance spectroscopy of the coated steel plates during immersion showed corrosion rates and coating permeability followed LAP > MMT > VMT formore »« less

Formation of metal oxides by cathodic arc deposition

Conference Anders, S ; Anders, A ; Rubin, M ; ...

Metal oxide thin films are of interest for a number of applications. Cathodic arc deposition, an established, industrially applied technique for formation of nitrides (e.g. TiN), can also be used for metal oxide thin film formation. A cathodic arc plasma source with desired cathode material is operated in an oxygen atmosphere, and metal oxides of various stoichiometric composition can be formed on different substrates. We report here on a series of experiments on metal oxide formation by cathodic arc deposition for different applications. Black copper oxide has been deposited on ALS components to increase the radiative heat transfer between themore »« less

Improvement of corrosion resistance of transparent conductive multilayer coating consisting of silver layers and transparent metal oxide layers

Journal Article Koike, Katsuhiko ; Yamazaki, Fumiharu ; Okamura, Tomoyuki ; ... - Journal of Vacuum Science and Technology. A, International Journal Devoted to Vacuum, Surfaces, and Films

An optical filter for plasma display panel (PDP) requires an electromagnetic shield with very high ability. The authors investigated a transparent conductive multilayer coating consisting of silver (Ag) layers and transparent metal oxide layers. The durability of the multilayer sputter coating, including the silver layer, is very sensitive to the surrounding atmosphere. For example, after an exposure test they found discolored points on the multilayer sputter coatings, possibly caused by migration of silver atoms in the silver layers. In their investigation, they modified the top surface of the multilayer sputter coatings with transition metals to improve the corrosion resistance ofmore »« less
