Abstract
Urbana gradska atmosfera kao uzročnik ubrzane korozije je glavni „neprijatelj“ očuvanju spomenika kulture. U svrhu zaštite od korozije bakrenih spomenika, istraživanja se sve češće okreću kompaktnim i uređenim samoorganizirajućim monoslojevima (SAM) organskih tvari u ulozi zaštitnih slojeva na površini bakra. Cilj ovog rada bio je ispitati mogućnost korištenja SAM-ova linolelaitične kiseline kao oblika korozijske zaštite, te mogućnost umrežavanja formiranog sloja pomoću gama zračenja. Umrežavanje sloja se provodilo u svrhu povećanja kompaktnosti zaštitnog sloja te posljedično i povećanja korozijske zaštite. Ispitivanje utjecaja koncentracije kiseline te doze zračenja na korozijska svojstva uzoraka pokazalo je da je optimalna koncentracija linolelaitične kiseline 0,5 mg/mL, dok najprimjetnije poboljšanje otpora koroziji pokazuju slojevi dobiveni kod optimalne koncentracije i ozračeni pri 150 kGy. Mjerenja u vremenu su pokazala minimalno pogoršanje zaštitnih svojstava tih slojeva s protekom vremena.
Abstract (english)
Urban city atmosphere as a cause of accelerated corrosion is the main „enemy“ when it comes to conservation of culture monuments. Regarding corrosion protection of copper monuments, researches have lately been turning more and more to compact and highly ordered organic self-assembling monolayers in form of a protective coating on copper surface. The aim of this work was to examine the ability of corrosion protection by linolelaidic acid SAM, and the ability of crosslinking of formed layers using gamma irradiation. The goal of crosslinking was to increase the compactness of the protective layer, consequently increasing corrosion resistance. It has been shown that the optimum concentration of linolelaitic acid is 0,5 mg/mL, while the biggest increase in corrosion resistance can be seen in layers formed at optimum acid concentration and irradiated at 150 kGy. Measurements in time have shown that the protective properties of this kind of a layer are reducing very slowly in time.
