A Novel High Voltage SBS/PVDF based Flexible Triboelectric Nanogenerator

A novel flexible triboelectric nanogenerator (TENG) was designed and fabricated for energy harvesting applications. The TENG consists of polystyrene-block-polybutadiene-block-polystyrene (SBS) and polyvinylidene fluoride (PVDF) composite as negative layer and polydimethylsiloxane (PDMS) as positive layer. The SBS/PVDF was prepared by mixing SBS (25 wt%), PVDF (1 wt%) in Tetrahydrofuran (THF) solution and bar coated on to a copper film. Similarly, PDMS was prepared by mixing liquid pre-polymer with curing agent and bar coated on to an aluminum film. In this work, SBS was first time implemented in TENG application and the capability of the developed TENG in term of open circuit voltage (OCV) was investigated by subjecting it to a force of 30 N with a maximum OCV of 178 V.
