Bearing in mind environmental concerns and global trends in ecology, biodegradable polyesters have gained enormous attention as alternative to non-biodegradable, commercial polymers used mainly in packaging industry contributing to the worldwide environment pollution. However, substitution of conventional polymers with biodegradable polyesters is limited due to their inferior mechanical and barrier properties, which can be improved by the introduction of relatively small content of non-toxic nanofillers. Nevertheless, environmental pollution is not only affected by material itself, but also manufacturing and processing sector in terms of energy sustainability. In case of the latter, low energetic processes are nowadays preferential. Thus, using microwave irradiation as the more efficient energy source, which can lead to shortening of process time, has become currently investigated subject. In this thesis, microwave-assisted in-situ synthesis of biodegradable nanocomposites based on polycaprolactone and non-toxic clay nanoparticles (layered double hydroxides) was studied and described in detail in four subsections (4.1-4.4). The first subsection (4.1) describes one-pot synthesis of Mg2+ /Al3+ layered double hydroxides functionalized with highly microwave-absorbing ionic liquids. In order to improve...
