Abstract
U ovom radu provedena je esterifikacija površine mljevenih koštica masline (MKM) sa stearinskom kiselinom (SA). Dokazivanje provedene reakcije esterifikacije površine punila izvršeno je pomoću infracrvene spektroskopije s Fourierovom transformacijom (FT-IR). Uočene promjene FT-IR spektra modificiranih koštica masline (mMKM) u odnosu na MKM jasno ukazuju na uspješno proveden postupak esterifikacije nakon čega se modificirano punilo upotrijebilo za pripravu kompozita s polilaktidnom kiselinom (PLA). FT-IR spektroskopija je također upotrijebljena za ispitivanje interakcija između PLA i mMKM. Dodatak kao i povećanje sadržaja modificiranog punila nije dovelo do uspostave interakcija između komponenata kompozita, pa se buduća istraživanja moraju usmjeriti prema drugim modifikatorima ili postupcima modificiranja kako bi se dobili PLA kompoziti što boljih svojstava.
Abstract (english)
In this work, the esterification of olive stone flour surface (OSF) with stearic acid (SA) was performed. Analysis of successfully performed esterification of the filler surface was performed using Fourier transform infrared spectroscopy (FT-IR). The observed changes in the FT-IR spectrum of modified olive stone flour (mOSF) relative to OSF clearly indicate successful esterification process after which the modified filler was used to prepare poly(lactic acid) (PLA) composites. FT-IR spectroscopy was also used to investigate the interactions between PLA and mOSF. The addition as well as the increase in the content of the modified filler did not lead to the establishment of interactions between the composite components, so future research must be directed towards other modifiers or modification procedures in order to obtain PLA composites with better properties.
