dc.description.abstractNovi trendovi u polimernoj industriji podstiču upotrebu sirovina dobijenih iz bioobnovljivih izvora kao i prelazak na zelenu tehnologiju. Nezasićene poliestarske smole su najzastupljenije termoreaktivne smole u proizvodnji polimernih kompozitnih materijala. Otpadni materijali, kao što su ljuske preostale od upotrebe kokošijih jaja, nastaju u velikim količinama, pri čemu ne predstavljaju opasan otpad zbog čega su korišćena kao punila za proizvodnju polimernih kompozitnih materijala. Za sintezu matrice korišćene su itakonska kiselina, ćilibarna kiselina, neopentil glikol, pri čemu je kao reaktivni rastvarač korišćen dimetil itakonat. Karakterizacija dobijenih kompozitnih materijala se sastojala od mehaničkog ispitivanja jednoosnim istezanjem kao i savijanjem u tri tačke, dok su promene u hemijskoj strukturi ispitivane FTIR spektroskopijom, a stepen umreženja je određivan analizom sadržaja gel faze.sr
dc.description.abstractDevelopment of biobased thermoset polymers encourages the strategic use of biobased resources and migrating to greener technologies. Unsaturated polyester resins have an extensive array of properties which makes them the most used thermoset resins in the production of polymer composite materials. Waste materials, such as eggshells left over from the usage of chicken eggs, are abundant and non-hazardous materials which offer many benefits in potential use as a filler in developing a biobased composite material. Itaconic acid, succinic acid, and neopentyl glycol were employed in unsaturated polyester synthesis, while dimethyl itaconate was used as a reactive diluent. Characterization of the resulting composite materials included assessing mechanical properties (uniaxial tensile test, three-point bending test), FTIR spectroscopy, and gel content analysis.sr
