Electroactive Polymers for Corrosion Control is designed to help chemists and engineers prevent corrosion of metals. This book discusses electroactive polymers, electrically conductive polymers, and mechanisms of corrosion protection (passivation of metals). Professor Alan MacDiarmid, 2000 Nobel Laureate, presents a brief review of the history of electroactive materials with a general understanding of the synthesis of electroactive materials and corrosion in aqueous environments. Several authors explain the phenomena of corrosion and propose mechanisms by which electroactive polymers inhibit corrosion. Several studies include current state-of-the-art synthesis of electroactive polymers, and data supporting the prevention of corrosion in various media are discussed. In addition, new techniques for measuring the onset of corrosion are presented. Chapters in this volume represent a broad range of new electroactive materials used in corrosion prevention and techniques used to measure corrosion. Both materials scientists and engineers will find this book useful for understanding and preventing corrosion. Alternatives to traditional barrier coatings used to prevent or retard corrosion are also discussed. Although previously published books have focused on organic and inorganic barrier coatings to prevent corrosion, this book focuses exclusively on electroactive polymers and their performance in retarding corrosion. Electroactive polymers represent a new, environmentally friendly approach to corrosion prevention.

The objectives of this SERDP program (WP 1148) have been completed successfully. The synthesis, scale-up and characterization of new monomers based on a bis-amino derivative of poly-p-phenylene vinylene (PPV) called poly(2,5-bis(N-methyl-N-hexylamino)phenylene vinylene, (BAM-PPV) and oligomers of polyaniline have been completed. These polymers have been thoroughly characterized using advanced spectroscopic and analytical methods. The details regarding the EAP synthesis has been published in the literature for duplication including potential industrial use. BAM-PPV pretreatment coating on Al 2024-T3 processed from different solvents passed 336 hours neutral salt fog exposure. This test is required for new pretreatment coatings on aluminum alloys. Additional pretreatments were also studied including trivalent chromium pretreatment (TCP). BAM-PPV coatings in several cases exceeded the 336 hour requirement. BAM-PPV has also been incorporated into full military coating systems that include non-chrome primers and topcoats. These coatings have been tested against known controls such as chromium primers and TCP pretreatment with non-chrome primer and topcoat. BAM-PPV performed as well as the TCP pretreatment with non-chrome primer and topcoat. However, in both cases, each coating did not pass the 2000 hours neutral salt fog exposure test. When BAM-PPV was used with chromium primer and topcoat, this coating system lasted over 4000 hours in a neutral salt fog chamber. Studies by ENM, SVET and XPS showed evidence that BAM-PPV provides more than simply barrier protection to corrosive environments and may passivate the metal surface.

Chromate surface treatments and chromate-containing epoxy primers are often used for corrosion control of aluminum alloys. However, due to environmental concerns and adverse health effects surrounding such use of chromates, there is an intensive effort to find suitable replacements for chromate-based coatings. Electroactive conducting polymers (ECPs) continue to be of considerable interest as components of corrosion-resistant coating systems. ECPs, in addition to being conductive, are redox active materials, with potentials that are positive of iron and aluminum. Thus, as with chromate, interesting and potentially beneficial interactions of ECPs with active metal alloys are anticipated. Our group has been investigating several ECPs for their corrosion protective properties, with emphasis on solution processable polymers. In this final report, the results of long-term immersion, preliminary results of Prohesion(registered) exposure studies, and scanning vibrating electrode technique (SVET), also known as the current density probe (CDP), are described. The coating systems studied incorporated either poly (3-octyl pyrrole) (POP) or poly (3-octadecyl pyrrole) (PODP) as a primer coating of 2 to 3 micrometers thickness. Samples were also studied that utilized a polyurethane topcoat of ca. 20 micrometers thickness in conjunction with the ECP coating. In control experiments, a chromated-epoxy primer of 20 micrometers thickness replaced the ECP coating. The immersion solution for the aluminum 2024-T3 samples was dilute Harrison solution, consisting of 0.35% (NH4)2SO4 and 0.05% NaCl. For the cold rolled steel samples a 3% NaCl electrolyte was used for this study.

Corrosion is an expensive and potentially dangerous problem in many industries. The potential application of different nanostructured materials in corrosion protection, prevention and control is a subject of increasing interest. Corrosion protection and control using nanomaterials explores the potential use of nanotechnology in corrosion control.The book is divided into two parts. Part one looks at the fundamentals of corrosion behaviour and the manufacture of nanocrystalline materials. Chapters discuss the impact of nanotechnology in reducing corrosion cost, and investigate the influence of various factors including thermodynamics, kinetics and grain size on the corrosion behaviour of nanocrystalline materials. There are also chapters on electrodeposition and the corrosion behaviour of electrodeposited nanocrystalline materials. Part two provides a series of case studies of applications of nanomaterials in corrosion control. Chapters review oxidation protection using nanocrystalline structures at various temperatures, sol- gel and self-healing nanocoatings and the use of nanoreservoirs and polymer nanocomposites in corrosion control.With its distinguished editors and international team of expert contributors, Corrosion protection and control using nanomaterials is an invaluable reference tool for researchers and engineers working with nanomaterials in a variety of industries including, aerospace, automotive and chemical engineering as well as academics studying the unique protection and control offered by nanomaterials against corrosion. - Explores the potential use of nanotechnology and nanomaterials for corrosion prevention, protection and control - Discusses the impact of nanotechnology in reducing corrosion cost and investigates various factors on the corrosion behaviour of nanocrystalline materials - Provides a series of case studies and applications of nanomaterials for corrosion control
