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

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 .
