1 Synthetic and modified biopolymers. Research on the synthesis and physical (blend, composite) and chemical modification (block and branched copolymers, degradation, chain extension) of synthetic (PLA, PHA, PBAT, etc.) and natural (cellulose, starch, chitosan) biopolymers. The use of natural, waste fillers. Composites of biopolymers with heat-conducting carbon materials. Abrasive compositions based on biopolymers. Development of materials and testing the properties of these systems for specific applications. Research on mechanical, rheological and structural properties. Processing of biopolymers, including reactive processing. Investigations of hydrolytic, enzymatic and composting degradation. Modification to increase hydrolytic, thermo- and photo-oxidative stability. Chemical Engineering
2 Controlled methods of polymer synthesis. Research on the synthesis of polymer molecules using controlled polymerization methods (ATRP, AREGET ATRP, RAFT - in cooperation, ROP of lactones, cyclic carbonates and ethers) and chain grafting (click chemistry, coupling with DCC / EDC, etc.) in combination with controlled destructive methods within polyesters and polycarbonates. Block copolymers with mixable and immiscible blocks (phase separation). Synthesis of functional polymers, including polymer conjugates as drug delivery systems. Synthesis of systems acting as multifunctional and reactive modifiers of polyesters and polyamides. Research on the kinetics of polymerization. Detailed analysis of the structure of the obtained chains (including MALDI ToF and GPC with quadruple detection - branches, copolymers, Mn, Mw, DI, etc.) and morphological analysis of the obtained materials (SEM, AFM, Raman microscope, DLS). Determination of the mechanical properties of polymers and composites. Chemical Engineering
3 Hybrid polymers and composites. Synthesis and structural characterization of hybrid polymers based on metal carboxylates or organophosphates. Correlation of physicochemical properties and morphology with the structure of the organic substituent. Application in synthesis (as reactive polymers), modification of mechanical properties of organic polymers (fillers of different morphology), flammability (flame retardants), crystallization of organic polymers (nucleants). Research on the synthesis of organosilicon polymers, including silanized urethane prepolymers. The use of these systems to create composites with carbon materials with increased thermal conductivity. Production and testing of the properties of composites with increased thermal conductivity based on matrices of synthetic, rigid and flexible biopolymers. Manufacturing and testing of composites with abrasive properties based on matrixes of synthetic elastic biopolymers or viscoelastic resins - carbon dioxide derivatives. Chemical Engineering
4 Recycling and processing of plastics. Study of the impact of cycles in mechanical recycling on the change of mechanical properties (tensile, bending and compressive strength as well as impact tests) and rheological properties (plastometer, rheometer). Counteracting the loss of properties by the addition of reactive chain stabilizers and extenders (constructive modification). Research on chemical (raw material) recycling of aliphatic and aliphatic-aromatic polyesters (destructive methods). Scaling (reactive) processing of thermoplastics from a few grams (mini extruder) to several kg / h (twin screw extruder). Determination of rheological changes during the extrusion of (modified) plastics with the use of a mini extruder. Setting up the processing of thermoplastics (synthetic biopolymers, blends and composites) by means of extrusion, injection moulding, pressing and thermoforming. Research on the development of two-component inks for 3D printing using the Inkjet printing method. Chemical Engineering
