Abstract
U ovom radu provedena je površinska modifikacija magnezijeva hidroksida s različitim masenim udjelima stearinske kiseline (1%, 2%, 3%, 4%, 6%, 8%) u odnosu na magnezijev hidroksid. Primjenom infracrvene spektroskopije s Fourierovom transformacijom snimljeni su apsorpcijski spektri izvornog magnezijeva hidroksida, stearinske kiseline i površinski modificiranih uzoraka. Zatim su uzorci ekstrahirani s najmanjom i najvećom količinom stearinske kiseline, a s ciljem utvrđivanja načina adsorpcije stearinske kiseline na magnezijev hidroksid (fizikalno ili kemijski). Rezultati su pokazali da je sva stearinska kiselina kemijski adsorbirana na magnezijev hidroksid kojeg se koristi kao punilo u polimernim materijalima te se očekuje da polimerni materijali dobiveni s površinski modificiranim magnezijevim hidroksidom imaju bolja preradbena i uporabna svojstva.
Abstract (english)
In this thesis the surface modification of magnesium hydroxide with different weight ratios of stearic acid (1%, 2%, 3%, 4%, 6%, 8%) related to magnesium hydroxide was performed. Corresponding absorption spectra of magnesium hydroxide, stearic acid and surface modified samples were recorded using infrared spectroscopy with Fourier transformation. Then, the extraction of samples with lowest and highest quantity of stearic acid was prepared in order to establish the adsorption type of stearic acid on Mg(OH) 2 (physically or chemically). The results showed that all of stearic acid was chemisorbed on magnesium hydroxide, the common filler in polymeric materials. Polymeric materials obtained with surface modificated Mg(OH) 2 is expected to have better processing and application properties.
