1 Research on the synthesis and modification of polyhydroxyurethanes. Polyurethanes are one of the most important groups of plastics used in many fields. However, the currently used technologies for their production are based on the use of isocyanates, which are toxic and moisture sensitive, and their production requires the use of highly toxic phosgene and generates stoichiometric amounts of sodium chloride. In recent years, the search for new technologies that would eliminate the use of these harmful reagents continues. An alternative to traditional polyurethanes are environmentally friendly polyhydroxyurethanes. Among others, carbon dioxide and fatty acids derivatives are used for their synthesis,. The subject of the proposed thesis will be the synthesis of polyhydroxyurethanes with the use of multi(cyclic carbonates) in reaction with diamines and their characterization, followed by modification of free hydroxyl groups with functional groups giving them new properties.

2 Electrospun polymer structures for the manufacturing of biomaterials An important aspect of tissue engineering is the ability to imitate the fibrous extracellular matrix (ECM) in the way that fundamental principles of cell organization, survival, and function can be provided. One of the most important methods for the mimicking ECM is electrospinning. The doctoral thesis will cover the preparation of new polymeric biomaterials for medical applications (e.g. tissue scaffolds) using the electrospinning technique. As part of the research, the PhD candidate will synthesize new polymer structures based on carbon dioxide derivatives, and then optimize the parameters of the electrospinning process of nanofiber mats. An important aspect of the work will be the characterization of obtained structures, such as: assessment of the morphology of fibers, their porosity, strength, thermal and thermomechanical properties, biodegradability and biocompatibility. As part of the planned research, it will be possible to complete a research internship abroad. Chemical Engineering
3 Research on the synthesis of new polymeric systems derived from carbon dioxide In connection with the climate catastrophe we are witnessing, it is necessary to eliminate technologies based on fossil resources. On the other hand, there is a need for technologies that would reduce the concentration of carbon dioxide in the atmosphere. The proposed research area concerns the synthesis of new cyclic and multicyclic monomers and their use to obtain polymers of various structures, from linear to branched, and hybrid systems. Carbon dioxide and its simple derivatives such as dimethyl carbonate and ethylene carbonate will be used as the precursor of cyclic moieties. The obtained materials will be an alternative to the currently used polyurethanes or, thanks to their unique features, they will be used as modifiers of their properties. Chemical Engineering
4 Research on the synthesis and application of polymers and polymer networks based on oligocarbonate diols The work carried out in recent years by our team has shown the extraordinary potential of polyurethanes based on oligocarbonate diols to obtain elastomers and coatings with excellent adhesion, hydrolytic and oxidative resistance and abrasion resistance. These materials may also exhibit shape memory and have the potential to possess self-healing characteristics. Due to their biocompatibility, they are often used as biomaterials. The proposed scope of work will include the modification of the structure of poly (carbonate-urethanes) in order to obtain the self-healing feature. At the same time, research is proposed to improve their mechanical resistance by introduction of additional functional groups and creating interpenetrating polymer networks. These types of networks can exhibit interesting shape memory properties. Chemical Engineering
