Abstract
Cílem této bakalářské práce byla optimalizace směsí biodegradovatelných polymerů. Optimalizace byla provedena pro směs kyseliny poly(L-mléčné) (PLLA) s biodegradovatelným termoplastickým elastomerem na bázi polyesteru (TPE-E) v různém procentuálním poměru a také s přidáním kompatibilizátoru poly(ethylen-methylakrylát-glycidyl-methakrylát) (EMA-GMA). V rámci experimentální studie byly zhotoveny zkušební vzorky, u nichž se následně testovaly a zkoumaly jejich tahové vlastnosti, rázová a vrubová houževnatost a morfologie lomových ploch.
The aim of this bacheor thesis was optimization of bidegradable polymer blends. Optimization was carried out for the blend poly(L-lactide) acid (PLLA) with biodegradable thermoplastic elastomer based on polyester (TPE-E) in different percentages and also with the addition of aditive poly(ethylene-co-methyl acrilate-co-glycidyl methacrylate) (EMA-GMA). In experimental study, test specimens were subsequently tested and examined for their tensile properties, impact and notched toughness and fracture surface morphology.
