Surface Modification by Ordered Monolayers: New Ways of Protecting Materials Against Corrosion

Abstract: Metal/polymer composites are used in numerous technical applications. For example, polymer coatings on metal surfaces are used for corrosion protection, metal films on polymers inhibit static buildup, and polymers between two metals can serve as a “glue” for connecting materials that cannot be welded. Polymer/metal composites also play an important role in modern electronics. In condensers, polymers serve as insulating layers between metallic leads and are used to encapsulate entire electronic circuits. In all… Show more

“…At the delaminated interface the potential is pulled down to the defect potential, which is directly measure dby SKP (see e.g. [2]). Hence, for both coatings the incorporated PPy is electrochemically active and the anions can be released by electrochemical reduction, i.e.…”

“…Thus a closed electric circuit for an electron flow from the defect to the polymer/metal interface is established (see figure 2 and e.g. [2]). The potential is pulled down and oxygen reduction takes place and further degrades the interface, facilitating cation transport and decreasing the i-R drop along the delaminated interface.…”

“…OPCA also exhibit good affinity for Al 2 O 3 [121,[140][141][142][143][144][145] as well as anodized Al [127,146]. In the same way, OPCA can be used to modify the native oxide layer at the surface of metals, such as titanium, aluminum, iron, steel, copper, and brass [147][148][149][150][151][152][153][154][155][156]. Aluminosilicates, such as mica [157] and imogolite [158], have been modified using phosphonic acids.…”

“…4b-d), polarizes the interface zinc/coating into a potential range where oxygen reduction is inhibited. Oxygen reduction, namely its reactive intermediates such as OH radicals, is the key reaction of fast cathodic delamination [27][28][29]. Hence, this relatively high potential prevents the production of these reactive intermediates and thus also inhibits delamination.…”

“…Only when the redox potential of the reduced PEDOT is decreased sufficiently, oxygen reduction will set in. As the migration of the cations needed to keep the electronic circuit closed [29] will then have to occur along an interface not degraded by intermediates (such as OH radicals) of oxygen reduction, its progress is slow. For this reason also the reduction of the PEDOT will be very slow and this will significantly delay the onset of delamination of the coating.…”
