Abstract
Glavni cilj ovog rada bio je pripremiti kompozitne filmove od polietilena (PE) i polipropilena (PP) s ekstraktom ružmarina (ER) ekstruzijom kojom su dobiveni filmovi (PE/ER i PP/ER). Za određivanje interakcija polimera i ekstrakta u kompozitu korištena je infracrvena spektroskopija s Fourierovom transformacijom (FT-IR). Za otkrivanje utjecaja ekstrakta ružmarina na toplinske karakteristike polimerne matrice korištena je diferencijalna pretražna kalorimetrija (DSC). Na temelju karakterističnih PE i PP apsorpcijskih vrpci, njihovog intenziteta, oblika i položaja može se zaključiti da dodatak ER nije utjecao na strukturu polimerne matrice. DSC krivulje su pokazale da karakteristični prijelaz taljenja i kristalizacije polimerne matrice praktički ostaju nepromijenjeni nakon dodavanja ER. Time je ostvaren glavni cilj ovog rada.
Abstract (english)
The main objective of this work was to prepare the composite films of the polyethylene (PE) and polypropylene (PP) with rosemary extract (ER) via hot melt extrusion (PE/ER and PP/ER). In order to determine the interactions of polymer and extract in the composite the Fourier transform infrared spectroscopy (FT-IR) was utilized. Differential scanning calorimetry (DSC) was used to detect influence of ER on the thermal characteristics of polymer matrix. Based on the characteristic PE and PP absorption bands, their intensity, shape and position it can be concluded that ER addition had no effect on the structure of polymer matrix. DSC curves revealed that characteristic melting and crystallization transition of polymer matrix practically remained unchanged upon ER addition. Hence, the main goal of this work was achieved.
