The main goal of this work will be to create an active non-woven fabric based on biodegradable polymers and natural agents with the ability to inhibit the activity of pathogens affecting food quality. Such packaging material is intended to extend the shelf life and ensure the freshness of food before consumption. It is expected that the Ph.D. student will acquire knowledge and skills in the preparation of materials using techniques such as electrospinning and blowing spinning. In the characterization of materials, she/he will use microscopy methods (SEM, TEM, OM), thermal analysis methods (TGA, DSC), spectrometric (SEM-EDX, FTIR), and mechanical methods (tensile tests, DMA), or X-ray diffraction (XRD). Part of the work will be testing manufactured materials and, ultimately, studying their degradation after use. The student is expected to have general knowledge of polymer chemistry, material engineering, and characterization methods, knowledge of the English language, the ability to work in a dynamic team, and independence. The basic research projects (VEGA, APVV) and projects of international scientific and technical cooperation will support the thesis.
