Abstract
Cilj ovog rada bio je sintetizirati zaštitnu polimernu prevlaku nano-debljine na bakrenu elektrodu primjenom gama-zračenja. Prevlaka je rađena umrežavanjem samoorganizirajućih monoslojeva linolelaitične kiseline. Samoorganizirani monoslojevi su nanošeni na površinu bakrene elektrode metodom uranjanja. Uspoređivala se učinkovitost različitih prevlaka na bakru: oksidni sloj, odnosno prirodna zaštita bakra, samoorganizirani monosloj i monoslojevi umreženi različitim apsorbiranim dozama zračenja. Ispitivane su doze zračenja od 100 kGy, 120 kGy, 130 kGy, 140 kGy, 160 kGy i 180 kGy. Uzorci su ispitivani metodama Tafelove ekstrapolacije i elektrokemijske impedancijske spektroskopije (EIS). Rezultati su pokazali da samoorganizirani sloj linolelaitične kiseline pruža relativno dobru zaštitu bakru s djelotvornosti od 66 %. Dobivene vrijednosti djelotvornosti zaštite kod umreženih prevlaka ukazuju na vrlo visoku efikasnost zaštine prevlake u odnosu na neozračene uzorke i uzorke od čistog bakra. Najefikasnija zaštita je postignuta kod doze od 130 kGy gdje je postignuta djelotvornost od skoro 99 %.
Abstract (english)
The objective of this work was to synthesize a protective polymer coating of nano-thickness on a copper electrode using gamma radiation. The coating was made by crosslinking self-organizing monolayers of linoleic acid. Self-assembled monolayers were applied to the copper electrode surface by immersion. The efficiency of different coatings on copper was compared: oxide layer, ie natural protection of copper, self-organized monolayer and monolayers crosslinked with different absorbed radiation doses. Radiation doses of 100 kGy, 120 kGy, 130 kGy, 140 kGy, 160 kGy and 180 kGy were tested. The samples were examined by Tafel extrapolation and electrochemical impedance spectroscopy (EIS) methods. The results showed that the self-organized layer of linoleic acid provides relatively good protection of copper with an efficiency of 66 %. The obtained values of protection efficiency in crosslinked coatings indicate a very high efficiency of coating protection in relation to non-irradiated samples and samples of pure copper. The most effective protection was achieved at a dose of 130 kGy where an efficiency of almost 99 % was achieved.
