Abstract
Modifikacija svojstava polilaktidne kiseline (PLA) provedena je dodatkom modificiranih mljevenih koštica masline (mMKM) s ciljem priprave biorazgradljivog kompozita. Uspješno su pripravljeni polimerni kompoziti svih sastava pomoći na ekstruderu s rotirajućim cilindrom. Diferencijalna pretražna kalorimetrija (DSC) je primijenjena u istraživanju utjecaja različitih udjela mMKM na toplinska svojstva i kristalnost PLA. Toplinska svojstva i kristalnost PLA u kompozitima PLA/mMKM ukazuju na slabe interakcije izmeĎu punila i kompozita. Punilo mMKM u kompozitima PLA/mMKM ima samo ulogu zamjene dijela skupljeg materijala s jeftinijim. Toplinska postojanost kompozita istraživana je primjenom neizotermne termogravimetrije (TG). Kompoziti PLA/mMKM se razgraĎuju do tri stupnja razgradnje. mMKM pogoršava toplinsku postojanost polimernih kompozita. Buduća istraživanja treba usmjeriti k promijeni modifikatora ili postupka modifikacije površine MKM kako bi se uspostavile jače interakcije izmeĎu punila i polimerne matrice čime bi se dobila bolja svojstva polimernog materijala.
Abstract (english)
The modification of the properties of poly(lactid acid) (PLA) was performed by adding modified olive stone flour (mMKM) with the aim of preparing a biodegradable composite. Polymer composites of all compositions have been successfully prepared using a rotary cylinder extruder. Influence of different proportions of mMKM on the thermal properties and crystallinity was investigated using differential screening calorimetry (DSC). The thermal properties and crystallinity of PLA in PLA/mMKM composites indicate weak interactions between fillers and composites. The mMKM filler in PLA/mMKM composites has just the role of replacing a part of the more expensive material with a cheaper one. The thermal stability of the composite was investigated using non-isothermal thermogravimetry (TG). PLA/mMKM composites are degraded in three degradation stages. mMKM degrades the thermal stability of polymer composites. Future research should focus on changing the MKM surface modifier or surface modification process to establish stronger interactions between the filler and the polymer matrix to obtain better properties of the polymeric material
