ABSTRACT
Both ex-ante investigations as well as ex-post studies are needed in the area of advanced polymer materials, particularly (bio) degradable polymers, in order to increase efficiency and to define and minimise the potential failure of novel polymer products before and during specific applications. The after-use properties of such materials are also important and therefore in this study, the degradation of polylactide (PLA) films with different thickness and PLA-based films with poly[(R,S)-3-hydroxybutyrate] ((R,S)-PHB), both obtained by extrusion as well as samples of PLA and its blend with polyhydroxyalkanoate (PHA) obtained by 3D printing with different patterns (printing directions) were investigated. The materials were characterised by optical microscopy, gel permeation chromatography and differential scanning calorimetry analysis. The main aspect of this research is to elaborate on new strategies for the comprehensive characterisation of complex polymer systems obtained by different methods. Comparative studies have allowed conclusions to be drawn from research on various materials under similar conditions.
