Design of polyurethane composite foam obtained from industrial PET wastes and MXenes for EMI shielding applications.

ABSTRACT: The primary aim of this study was to synthesize and characterize polyurethane (PUR) foams derived from the depolymerization products of poly(ethylene terephthalate) (PET) and MXenes (Nb₂AlC). The depolymerized PET products were produced through a zinc acetate-catalyzed glycolysis process using diethylene glycol (DEG) as solvent. These glycolysis products were then reacted with 4,4'-diphenylmethane diisocyanate (MDI), commercial polyols, and MXenes to produce the PUR foams. The resulting materials were characterized using FT-IR, SEM, EDX mapping, mechanical testing, thermal analysis, and electromagnetic interference (EMI) shielding assessments. The analysis revealed that specimens with a higher concentration of the filler (3.55%) exhibited superior mechanical properties, while th
