Abstract
Samoorganizirajući monoslojevi (SAM) dugolančanih organskih kiselina nastaju adsorpcijom kiseline na površini oksida metala što dovodi do kiselinsko- bazne reakcije između oksida metala kiseline. Samoorganizacijom alkilnih lanaca stvara se tanak i kompaktni film za površini. Samoorganizirajući monoslojevi su jednostavna i novija metoda zaštite materijala, imaju široku primjenu u biologiji, elektronici, nanoelektromehaničkim i mikroelektromehaničkim sustavima i u elektrokemiji. Pokazali su se kao dobri inhibitori korozije na raznim metalnim podlogama U ovom radu istraživan je utjecaj sastava metalne podloge na formiranje zaštitnog filma dugolančane fosfonske kiseline. Na taj način nastojalo se poboljšati korozijsku stabilnost uzoraka CuSn6 i PbCu bronci i čistog bakra u umjetnoj kiseloj kiši. Metodom elektrokemijske impedancijske spektroskopije praćeno je korozijsko ponašanje ispitivanih bronci i bakra sa i bez filma16-fosfonoheksadekanoične kiseline.
Abstract (english)
Self-assembled monolayers (SAM) of long-chain organic acids are formed by the adsorption of acid on the surface of oxide-covered metal, resulting in acid-base reaction between metal oxide and acid. Self-organization of alkyl chains creates a very thin and compact film. Self-assembled monolayers are a simple and new method of material protection, used in many fields such as application in biology, electronics, nanoelectromechanical and microelectromechanical systems and in electrochemistry. They have proven to be good corrosion inhibitors on various metal substrates In this paper, the influence of the composition of the metal substrate on the formation of a protective film of long-chain phosphonic acid is investigated. In this way, efforts were made to improve the corrosion stability of CuSn6 and PbCu bronze samples and pure copper in artificial acid rain. The electrochemical impedance spectroscopy is used to examine the corrosion behaviour of studied bronzes and copper with and without the 16-phosphonohexadecanoic acid film.
