“…These sensors are employed in different analytical determinations [2,3] after being stored for long time periods in the working solution. However, a loss of conductivity was observed as the storage time of POAP was extended beyond 30 h. The loss of conductivity of POAP was studied in our laboratory by employing different electrochemical techniques [5][6][7]. Results about POAP deactivation are reviewed here.…”

Objective: Storage time without use (STWU) in the supporting electrolyte solution for time periods beyond 30 hours deactivates poly(o-aminophenol) (POAP) films.Observations: Deactivated POAP films exhibit a lower conductivity than freshly prepared (nondeactivated) films Considering the interest in POAP synthesized in acid medium in both basic and applied research, not much attention has been paid to the decay of the electroactivity of POAP caused by its extensive use. Conclusion: Deactivation of poly(o-aminophenol

“…The effect of the plasma treatment on the failure process of alkyd-varnish coatings (AVCs) with defects under deep-ocean conditions was investigated. EIS [16][17][18][19] and SKP [20][21][22][23][24] were used as electrochemical macroscopic and microscopic characterization methods, respectively. The depth-from-defocus method was also applied as an intuitive approach to observing the changes in the defects and the coating.…”

Electrochemical impedance spectroscopy (EIS) and scanning Kelvin probe (SKP) were used to study the failure of the coating modified with air-plasma treatment in 3.5 % mass fraction of NaCl. The results show that the failure process can be divided into three stages including water penetration, accumulation of corrosion products at the location of a defect, water penetration of the entire coating and coating failure. The EIS results show that the plasma-treated samples exhibit an additional electrical double-layer capacitor that delays the coating failure during the second stage. The potential of the non-plasma-treated samples decrease faster than that of the plasma-treated samples according to the SKP study. As the transition layer, air plasma delays the coating failure due to the chemical bond between the metal substrate and the coating. Keywords: air-plasma treatment, electrochemical impedance spectroscopy, scanning Kelvin probe, coating failure, hydrostatic pressure Elektrokemijsko impedan~no spektroskopijo (angl. EIS) in vrsti~no Kelvinovo sondo (SKP) smo uporabili za preu~evanje po{kodb na prevleki, modificirani s plazmo, v 3,5 mas. % raztopini NaCl. Rezultati ka`ejo, da se nastajanje po{kodb lahko razdeli na tri faze, vklju~no s penetracijo vode: na akumulacijo korozijskih produktov na mestu napake, na prodiranje vode v dele celotne prevleke in na odpoved prevleke. Rezultati EIS ka`ejo, da imajo vzorci, obdelani v plazmi, dodaten elektri~ni dvoslojni kondenzator, ki v drugi fazi upo~asni po{kodbo prevleke (premaza). SKP-analize so pokazale, da se potencial plazemsko neobdelanih vzorcev zmanj{uje hitreje kot tistih vzorcev, ki so bili obdelani s plazmo. Kot prehodna plast, obdelava z zra~no plazmo upo~asni po{kodbo premaza zaradi kemijske vezi med kovinskim substratom in prevleko. Klju~ne besede: obdelava s plazmo, elektrokemijska impedan~na spektroskopija, skeniranje s sondo Kelvin, odpoved prevleke, hidrostati~ni tlak
