Today, among the bioplastics (biopolymers), polylactic acid (PLA), which is a brittle polymer, is the most common. In order for the PLA bioplastic to be able to replace traditional plastics, it definitely needs to be modified. In my work, I added several types of bioplastics to PLA (tough rubber-like and flexible) and examined the properties of test specimens produced by injection molding from a three-phase bioplastic blend.
Kivonat
Napjainkban a bioműanyagok (biopolimerek) közül a politejsav (PLA – PolyLactic Acid) a legelterjedtebb, amely egy rideg polimer. Azért, hogy a PLA bioműanyag képes legyen helyettesíteni hagyományos műanyagokat, úgy mindenképpen a módosítására van szükség. Munkámban a PLA-hoz többféle bioműanyagot adtam (szívós gumiszerű, valamint rugalmas) és vizsgáltam a háromfázisú bioműanyag keverékből fröccsöntéssel előállított próbatestek tulajdonságait.
