Original Abstract

Today, society is very focused on recycling and using reusable or eco-friendly options to replace plastics. However, these will not be easy to eliminate from everyday life. A possible way forward is to introduce more environmentally friendly or reusable materials. These materials include biopolymers and biobased polymers. However, their problem is the high purchase price or the need to modify the properties of the polymer for the desired behavior. These polymers are receiving a high level of attention and are the focus of many studies and projects. This post investigates the degradation characteristics of polyester polymers (PBS with incorporated dilinoleic succinate in different %wt.) in simulated body fluids, revealing minor changes in properties. Bacterial degradation was also investigated, and analysis shows more significant differences in Gel Permeation Chromatography (GPC) and Scanning Electron Microscope (SEM) results. A few changes in properties were observed in FTIR spectroscopy and thermal analysis, as Differential Scanning Calorimetry (DSC) and Dynamic-Mechanical Thermal Analysis (DMTA). While abiotic degradation predominates, bacterial environments lead to higher degradation levels than simulated body fluids, suggesting potential applications in packaging or agriculture. However, lower sensitivity to abiotic degradation opens new possibilities for further research into exploring bacterial and enzymatic degradation mechanisms for environmentally sustainable alternatives across industries.
