Polyurethanes synthesized using biomass-derived furan diols as sustainable triboelectric materials

Abstract

This work shows that various polyurethanes (FPUs) prepared using biomass-derived furan diols can be applied as promising tribopositive materials. The elastic FPUs having appropriate glass transition temperature (T_g) could be incorporated into polyethylene terephthalate (PET) fabrics to form FPU/PET films. The optimal FPU-4/PET film showed promising triboelectric performance with output voltages (V_p–p) up to 405 V and a maximum power density (P_max) of 32 mW cm⁻².
