摘　　要：Contact electrification is a direct triboelectrification method for producing current through charge transfer when two different differentiated materials have brought into contact.For the first time,we developed a simple triboelectric nanogenerator(TENG)where the electronic charges were realized through contact separation mode between sand-polished Kapton(SPK)and Al surface.Here,we demonstrated the energetic interfacial contact between these surfaces and observed satisfactory output performance.The novel SPK-TENG produced 40 V and 2.8μA,of open-circuit voltages(V_(oc))and short-circuit currents(Isc)at 4 Hz,respectively.Mainly,the SPK-TENG was dramatically increased up the performance of TENG,up to 40% of V_(oc) and 42% of I_(sc),with respect to the Kapton film because the mobility of electrons is very high on the device surface compared to the other pristine Kapton film.The fabricated SPK-TENGs were good candidates for satisfying the need for alternative contact separation mode TENGs.
