Abstract

Corrosion protection using conventional coatings is the most used method. Application of polyaniline (PANI) as an inhibitor in conventional coating is based on its proven and well examined protective nature, with motivation for replacement of hazardous materials used as inhibitors. Experimental procedures for investigation of the influence of PANI in coatings are focused both on evaluation of physical properties of the coatings studied by FTIR, Raman and UV spectroscopy, thermogravimetric analysis, SEM and TEM microcopies, while the protective nature of the coating, applied at the first place on steel, is studied by accelerated corrosion testing using humidity and salt chamber, electrochemical impedance spectroscopy and polarization measurements upon immersion in corrosion media. Primena sistema klasičnih organskih prevlaka za zaštitu metala i legura od korozije je najrasprostranjeniji vid zašte. Primena inhibitora korozije na bazi polianilina (PANI) je zasnovana na njegovom eksperimentalno potvrđenom zaštitnom dejstvu. Osnovni motiv za primenu PANI je zamena ekološki neprihvatljivih materijala koji se korite kao inhibitori. Eksperimentalna istraživanja u ovoj oblsti bazirana su na proučavanju fizičkih svojstava prevlaka primenom spektoskopskih tehnika: FTIR, Ramanske spektroskopije i UV spektroskopije, termogravimetrijske analize, SEM i TEM mikroskopija, dok se ispitivanja zaštitnih svojstava prevlaka na baziraju na ubrzanim korozionim testovima primenom slane i vlažne komore, eksperimentima spektroskopije elektrohemijske impedancije i polarizacionim merenjima.
