The chemical conversion of CO2 into valuable chemicals has attracted great attention from scientists. In this work, cyclic carbonates (CCs) with various functional groups were prepared through the epoxides. By reacting CCs 2-ethanolamine, carbamate diols (CDs) could be developed as polymer platforms. Finally, a series polyurethanes (PU-CDs) synthesized by CDs diisocyanate and applied triboelectric energy harvesting materials. performance PU-CDs on polyethylene terephthalate fabric (PET-F) films depended PU-CDs. optimal PU-CD4/PET-F film phenyl exhibited promising performance, achieving an output peak-to-peak voltage (Vp–p) 352 V maximum power density 18 mW/cm2. devices fabricated demonstrated excellent durability over 30000 pressing/releasing cycles able to green light emitting diodes (LEDs) hygrometer. Based synthetic strategy greater variety CO2-derived PUs can designed for energy.

This study aims to investigate the potential of integrating natural biochar (BC) derived from eggshell waste into flexible polyurethane (FPU) foam enhance its mechanical and acoustic performance. The explores impact incorporating BC at various weight ratios (0.1, 0.3, 0.5, 0.7 wt. %) on properties FPU foam. Additionally, effects modifying with (3-aminopropyl)trimethoxysilane (APTMS) different (10, 20, 30 influence diverse particle sizes thermal, mechanical, characteristics composite are investigated. functional groups, morphology, elemental composition developed composites analyzed using Fourier-transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX) techniques. Characteristics such as density, gel fraction, porosity were also assessed. results reveal that density increased by 4.32% 7.83% while decreased 50.22% 47.05% addition 0.1 % unmodified modified 20 APTMS, respectively, compared unfilled FPU. fraction matrix increases 1.91% 3.55% inclusion respectively. Furthermore, TGA analysis revealed all demonstrate improved thermal stability FPU, reaching a peak value 312.17°C for sample APTMS. Compression strength untreated but higher concentrations. Modifying 20% APTMS resulted in an 8.23% increase compressive Acoustic showed absorption, enhanced absorption Class D mm thickness. further (Class E), modification showing best results. These present promising materials sound applications address environmental issues related waste.
