Abstract
Pripravom kompozitnih mješavina polimernih materijala s punilima moguće je poboljšati njihova mehanička, toplinska, zaštitna, te ostala uporabna svojstva. Cilj ovog diplomskog rada je istražiti pripravu nanokompozitnog materijala na osnovi mješavina polilaktida (PLA) i polikaprolaktona (PCL) sa cinkovim oksidom (ZnO) kao nanopunilom, te karakterizirati mehanička, toplinska, i zaštitna svojstva prevlaka napravljenih od navedenih nanokompozita. PLA/PCL/ZnO kompoziti su pripravljeni s različitim masenim udjelima komponenata u otopini kloroforma. Provedena su vlačna ispitivanja mehaničkih svojstava, te toplinska svojstva primjenom termogravimetrijske anlize (TGA) i diferencijalne pretražne kalorimetrije (DSC) na filmovima debljine 4 μm. Prevlake su nanesene na metalne pločice od aluminija, bakra, i ugljičnog čelika, te su njihova zaštitna svojstva ispitana primjenom elektrokemijske impenancijske spektroskopije(EIS). Utvrđena su značajna poboljšanja mehaničkih svojstava kompozitnog materijala u odnosu na čiste polimere i njihove mješavine, te su utvrđena dobra zaštitnih svojstava i stabilnosti prevlaka.
Abstract (english)
The preparation of polymer mixtures with ZnO nanofiller it is possible to improve their mechanical, thermal, protective, as well as other usable properties. The aim of this master’s thesis is to investigate the preparation of nanocomposite material with a polylactide (PLA) and polycaprolactone (PCL) polymers with zinc oxide (ZnO) as the nanofiller, and characterize the mechanical, thermal, and protective properties of its coatings. PLA/PCL/ZnO nanocomposites are prepared with different mass ratio of components by mixing in chloroform as the solvent. Tensile, termogravimetric (TGA) and differential scanning calorimetry (DSC) testing were performed on films 4 μm thick. The coatings are applied on metal plates from aluminium, copper and carbon steel, after which their protective properties are investigated through electrochemical impedance spectroscopy (EIS) It is determined that there is a noticeable improvement in the mechanical properties of the composites in comparison to the pure polymers and their mixtures, and there has been no degradation of protective properties and thermal stability.
