Molecularly imprinted polymers (MIP) were obtained by precipitation polymerization for the detection of DEHP and DBP from polymer packaging in drinking water. MIP was obtained by cross-linking DEHP and DBP with methyl methacrylate (MMA) and trimethylolpropane trimethacrylate (TRIM). FTIR, SEM-EDS, UV-Vis and SAA were used to determine properties of polymers (MIP_DEHP, MIP_DBP). The obtained materials were characterized by a mesoporous structure with small, uniform, and porous grains. The surface area and total pore volume of MIP_DEHP were more than twice smaller than MIP_DBP, with a slightly larger pore diameter. Lower C content may indicate the formation of MIP_DEHP and MIP_DBP. The FTIR method confirmed the presence of functional groups –CH, –CO, –C=C and –C=O. The adsorption capacity of MIP_DEHP and MIP_DBP was 0.68 mg/g and 1.06 mg/g, respectively, and was consistent with the Freundlich isothermal adsorption model.

A new functionalized biopolymer was obtained by adding ethylenediaminetetraacetic acid to chitin and magnetite nanoparticles (Fe3O4). Thermogravimetric analysis was performed, and dielectric properties were examined. The obtained biopolymer showed better thermal stability, as evidenced by a higher onset temperature. The activation energy calculated using imaginary impedance data and Nyquist plots was found to be consistent. Moreover, the dielectric permittivity decreased rapidly with increasing frequency. At high frequencies, there was no dependence of dielectric loss on temperature and frequency. The obtained biopolymer can be used in many applications such as microwave devices, deflection yoke, high-frequency capacitors, sensors, etc.

The effect of compatibilizer - ethylene-n-octene copolymer grafted with maleic anhydride(EOC-g-MAH) used in the amount of 3 wt% on tensile and flexural properties and impact strengthof bioPET with the addition of 10 wt% filler derived from organic waste (egg and mollusc shells, coffeegrounds) was investigated. EOC-g-MAH slightly decreased tensile strength, flexural strength, andmodulus of elasticity, while significantly increasing impact strength (up to 426%). Moreover, ability ofbioPET-based composites to dissipate mechanical energy was improved.

The effect of aromatic ring substitution in the polyester polyol molecule on its physicochemicalproperties and on the conditions of synthesis, fire resistance and thermal stability of polyurethanefoams was investigated. The greater number of terephthalic units in the polyol results in greater viscosityand reactivity during foam formation. The obtained foams were characterized by higher thermalstability (TGA) and fire resistance (oxygen index, single flame test).

Composites based on PLA with the addition of 3, 6 and 10 wt% silica, hydroxyapatite and bentonite were obtained by twin-screw extrusion. Maleic anhydride grafted polyethylene was used to enhance interface interactions. The influence of the fillers used on the Charpy impact strength, Rockwell hardness, tensile properties and processing shrinkage was investigated. Test samples were obtained by 3D printing. The highest impact strength and hardness were obtained for the composite containing 10 wt% hydroxyapatite. PLA with 10 wt% hydroxyapatite and 3 wt% bentonite was used to obtain anatomical structures by 3D printing.

The aim of the study was to evaluate the shrinkage stress during cross-linking of compositeorthodontic adhesive systems. The elastic-optical method was used for shrinkage stress analysis. Basedon the obtained results, basic statistics were determined, including averages and standard deviations.For the comparative analysis of the mean values, the Tukey HSD test was used at the significance levelα = 0.05. The average value of shrinkage stress during cross-linking ranged from 7.2 to 11.5 MPa.

The effect of fumed silica (3 and 5 wt%) on the structure, viscosity, tensile and flexural properties, and hardness of photosensitive acrylic resins used for 3D printing was investigated. The optimal set of functional properties was obtained with a silica content of 3 wt%. In this case, the resin had the appropriate viscosity, degree of cross-linking, hardness (90 ShD), tensile strength (47 MPa) and flexural strength (96 MPa). The obtained results indicate that the addition of silica effectively reinforce the resin.
