Abstract

Vedno bolj je aktualen razvoj pametnih materialov ter bio-osnovanih materialov, ki dosegajo odlične termo mehanske lastnosti. V diplomski nalogi sem sintetizirala bio-osnovan benzoksazin ter raziskala mehanske lastnosti in oblikovni učinek kopolimera benzoksazina in epoksidne smole. Za proučevanje mehanskih lastnosti in oblikovnega učinka sem uporabila dinamično mehansko analizo (DMA). Zamrežen benzoksazin na osnovi rezorcinola in stearilamina ni izkazal najboljših mehanskih lastnosti, sem pa s termomehanskimi cikli DMA potrdila in ovrednotila oblikovni učinek. Vzorec je dosegel visoko razmerje zadržane oblike (90–92 %) in visoko razmerje obnovljene oblike (72–98 %).

Secondary abstract: The development of smart materials and bio-based materials, which achieve excellent thermal and mechanical properties, is increasingly relevant. In my thesis, I synthesized bio-based benzoxazine and investigated the mechanical properties and shape memory effect of the copolymer of benzoxazine and epoxy resin. I used dynamic mechanical analysis (DMA) to study the mechanical properties and shape memory effect. The cross-linked benzoxazine based on resorcinol and stearylamine did not show the best mechanical properties, but with thermomechanical DMA cycles, I confirmed and evaluated the shape memory effect. The sample achieved a high shape-fixing ratio (90–92%) and a high shape recovery ratio (72–98%).
