Utjecaj PCL-a na svojstva PA/PCL mješavina

Abstract

The aim of this thesis is to investigate the influence of polycaprolactone (PCL) on the properties of polyamide 12 (PA12) and polycaprolactone (PCL) blends, with special emphasis on their thermal, surface, and mechanical properties. Polymer blends are increasingly used in industry as they enable the combination of beneficial properties of different polymers, resulting in materials tailored to specific needs and applications. PA12 is a thermoplastic polymer known for its high strength, chemical resistance, and stability, while PCL, a biodegradable polymer, contributes to the flexibility and easier processing of the material. The use of these polymer blends opens up the possibility of creating new materials with improved properties suitable for various industrial applications, including medical devices, packaging, automotive, and aerospace industries. In order to thoroughly investigate the properties of the blends, tests were conducted using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which provide insight into the thermal stability and transition temperatures of the materials. Additionally, surface properties were analyzed by measuring the contact angle to calculate the surface free energy, while mechanical properties were determined through tensile testing. This thesis contributes to a better understanding of the behavior of PA12/PCL polymer blends and provides a foundation for further research focused on the compatibility of components within the polymer blend, as well as its stability and industrial application.

Cilj ovog rada je istražiti utjecaj polikaprolaktona (PCL) na svojstva mješavina poliamida 12 (PA12) i polikaprolaktona (PCL) s posebnim naglaskom na njihova toplinska, površinska i mehanička svojstva. Polimerne mješavine sve se više koriste u industriji jer omogućuju kombiniranje korisnih svojstava različitih polimera, čime se postiže materijal prilagođen specifičnim potrebama i primjenama. PA12 je termoplastični polimer poznat po visokoj čvrstoći, kemijskoj otpornosti i stabilnosti, dok PCL, biorazgradivi polimer, doprinosi fleksibilnosti i lakšoj obradi materijala. Korištenje mješavina ovih polimera otvara mogućnost stvaranja novih materijala s poboljšanim svojstvima koja su pogodna za različite industrijske primjene, uključujući medicinske uređaje, ambalažu, automobilsku i zrakoplovnu industriju. Kako bi se detaljno istražila svojstva mješavina, provedena su ispitivanja pomoću diferencijalne pretražne kalorimetrije (DSC) i termogravimetrijske analize (TGA), koji pružaju uvid u termičku stabilnost i prijelazne temperature materijala. Također, površinska svojstva analizirana su mjerenjem kontaktnog kuta radi izračunavanja slobodne površinske energije, dok su mehanička svojstva određena kroz test vlačnog ispitivanja. Ovaj diplomski rad doprinosi boljem razumijevanju ponašanja polimernih mješavina PA12/PCL te pruža temelje za daljnja istraživanja usmjerena na kompatibilnost komponenata unutar polimerne mješavine te njenu stabilnost i industrijsku primjenu.
