Annotation Tato bakalářská práce je změřena na návrh a praktické ověření metody vizualizace sférolitické struktury na rovinném řezu a lomové ploše polymeru, konkrétně polypropylenu. Na základě provedených experimentů je třeba konstatovat, že nebyla nalezena dostatečně účinná metoda. Dalším cílem této práce je ověření a pokus o zpřesnění parametrů Avramiho rovnice popisující časovou závislost krystalizace polymerů pomocí metody maximalizace regresního koeficientu a metodou minimalizace sumy čtverců odchylek. Aplikací těchto metod bylo zjištěno, že původní hodnoty parametrů Avramiho rovnice se jeví jako nejpřesnější.
Annotation in English This Bachelor thesis is focused on proposal and practical verification of method of visualization of spherulitical structure on planar cut and fracture area of polymer, concretely polypropylene. On the basis of experiments made, it is necessary to state, that enough effectual method was not found. The next target of this work is a verification and attempt of improvement of parameters of Avrami equation, which describes time dependence of polymer crystallization, by the help of the method of maximization of regression coefficient and the method of minimisation of square of deviation. After application of this methods was found, that the original values of Avrami equation‘s parameters looks as the most exact.
Keywords Polypropylen, sférolit, krystalizace, Avramiho rovnice, elektronová mikroskopie, numerické simulace.
Keywords in English Polypropylene, spherulite, crystallization, Avrami equation, electron microscopy, numerical simulation
