Abstract
Cilj ovoga rada bio je ispitati svojstva čistih komponenata polilaktida (PLA-S, PLA-N), polietilena visoke gustoće (PE-HD) i polietilena niske gustoće (PE-LD). Također, su ispitana svojstva pripremljenih polimernih mješavina PLA-S/PE-HD, PLA-S/PE-LD, PLA-N/PE-HD i PLA-N/PE-LD 95/5 i 90/10 bez i uz dodatak punila (TiO2, silika). Uzorci su umješavani u Brabender gnjetilici. Određena su mehanička i toplinska svojstva čistih komponenata i pripremljenih polimernih mješavina. Također, je ispitana morfologija na temelju mehaničkih svojstava odabranih uzoraka. Snimljeni su FTIR spektri čistih komponenata. Na temelju dobivenih rezultata zaključeno je da polimerne mješavine bez dodatka punila imaju manju prekidnu čvrstoću i rad loma u odnosu na čiste komponente. U mješavinama PLA-N kao bolje punilo se pokazao TiO2, dok je u mješavinama s PLA-S kao bolje punilo odabrana silika. Proučavanjem morfologija mješavina, zaključeno je da najveći utjecaj na mehanička svojstva ima raspodjela veličina čestica i dispergiranost faza.
Abstract (english)
The aim of this study was to determine the properties of 95/5 and 90/10 PLA-S/PE-HD, PLA-S/PE-LD, PLA-N/PE-HD and PLA-N/PE-LD polymer mixtures prepared without and with filler addition (TiO2, silica). Also, properties of pure polylactide (PLA-S, PLA-N), high density polyethylene (PE-HD) and low-density polyethylene (PE-LD) have been tested. Samples were blended in the Brabender mixer. Mechanical and thermal properties of pure components and prepared polymer blends were obtained. The morphology of selected samples was tested. FTIR spectra of pure components were recorded. Based on the obtained results, it was concluded that the polymer blends without the addition of filler have lower strength at break than the pure component. In PLA-N blends, TiO2 has been shown, as a better filler, while in PLA-S blends silica was a better choice. Morphology studies showed that particle size distribution and phase dispersion have the greatest influence on the mechanical properties of the blends.
