Abstract<\/strong><\/p>\n

The aim of this study was to synthesize and investigate medical-grade polyurethane-urea foams (PUUFs) with immobilized decamethoxin (DCM). The PUUFs were prepared using mixtures of macrodiisocyanates MDI(I) and MDI(II) at molar ratios of 1:1, 2:1, and 3:1, followed by the addition of 1 wt.% DCM. A comprehensive characterization was performed, using physicomechanical testing, differential scanning calorimetry (DSC), and FTIR spectroscopy. It was established that the MDI(I):MDI(II) ratio of 1:1 provided the optimal tensile strength (\u03c3 = 0.43 MPa), elongation at break (\u03b5 = 360.3 %), and adhesive strength (\u03c4 = 6.30 MPa). The incorporation of decamethoxin led to a decrease in tensile strength and elasticity, which is attributed to structural rearrangements within the polymer matrix. FTIR analysis showed changes in the intensities of NH and C=O absorption bands involved in hydrogen bonding, with no new bands appearing, indicating that DCM immobilization occurs mainly through physical interactions. DSC results showed changes in the glass transition temperature (T<\/em>g<\/sub>) and \u0394C<\/em>p<\/sub> values, indicating alterations in segmental mobility and intermolecular interactions when DCM is present. The obtained materials exhibited a single-phase structure. Despite a moderate decrease in mechanical properties, the DCM-containing compositions maintained sufficient performance characteristics and can be considered promising antimicrobial polyurethane systems for developing medical adhesives and materials with prolonged local therapeutic effects.<\/p>\n
