BNO-SPI-TENGs for Robust Contact Electrification by Vertical Contact Separation Mode Through Ion and Electron Charge Transfer
Contact-electrification is a conventional triboelectrification technique for generating current through charge transfer when two different polarized materials are brought into contact.For the first time,in-built alternate hydrophilic and hydrophobic nano channels were developed where both ionic and electronic charge transfer mechanisms were realized through contact separation mode between BNO-SPI films and PTFE.In this paper,we examined the dynamic interaction between these materials and observed adequate output performance.The novel BNO-SPI-TENGs(i.e.SO3H.BNO-SPI-TENG,SO3Li.BNO-SPI-TENG,and SO3H.TEA.BNO-SPI-TENG)produced 75 V and 1 μA,43 V and 0.6 μA,and 9 V and 0.13 μA of open-circuit voltages(Voc)and short-circuit currents(Jsc)at 6 Hz,respectively.Particularly,the SO3H-BNO-SPI was dramatically boosted up the performance of TENG,up to 733%of Voc and 669%of Jsc,with respect to the SO3H.TEA-BNO-SPI because the mobility of H+ions is very high on the device surface compared to the other two Li+and TEA bulky ions.The developed dual characteristic BNO-SPI-TENGs are very good candidates for fulfilling the need for alternate contact separation mode TENGs.
