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 2.8 µA, of open-circuit voltages (V oc ) and short-circuit currents (I sc ) 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. ARTICLE HISTORY

nitride (InN) nanowire energy harvesters [8][9][10][11][12][13][14] ; 2) triboelectric-based generators with multiple electrification pairs or a sliding Schottky nanocontact [15][16][17] ; 3) conducting polymer-metal Schottky diodes. [18,19] In our previous studies, we have demonstrated that a conducting polymer film when forming a Schottky contact with a metal (such as Al or Al alloy) can produce DC outputs under compressive deformations. [18,19] The devices showed a large energy density. They are easy to fabricate, offering great potential for applications in various self-powered electronic devices.Polyaniline (PANI) is a major conducting polymer possessing high conductivity and processing ability. [20] It has shown vast application potential in the fields of supercapacitors, batteries, sensors, EMI shielding, and gas separation. [21][22][23] PANI can be easily doped and de-doped. The dopant and doping state have a great effect on the electrical properties of PANI. [24] For example, PANI emeraldine base (PANI-EB), i.e., non-doped PANI, is almost nonconductive with an electrical resistivity as high as 10 10 Ω cm −1 . [25] The conductivity is largely enhanced when doped with a protonic acid. [26] The dopant effect was attributed to the change of PANI crystallinity, interchain distance, and energy bandgap, hence leading to change in chemical and physical properties (e.g., electrochemical, spectroscopic, and modulus). [24,27,28] However, how dopant affects the energy conversion property of PANI-metal Schottky diodes has not been reported in research literature.In this study, we have for the first time demonstrated the effect of dopants on the mechanical-to-electrical energy conversion behavior of a conducting polymer-metal Schottky power generator. PANI was used as a conducting polymer model, which was doped with four protonic acids; orthophosphoric acid (H 3 PO 4 ), sulfuric acid (H 2 SO 4 ), perchloric acid (HClO 4 ), and hydrochloric acid (HCl). The dopants showed a great effect on energy conversion property. The device made of nondoped PANI only produced up to 1.5 mV and 0.55 nA cm −2 electrical outputs. The one from HCl-doped PANI generated much higher outputs (0.9 V and 33.9 µA cm −2 ) than those from PANI doped with other protonic acids. The change in electrical outputs was attributed to the effect of dopant on barrier height and conductivity. For Al/PANI-HCl/Au, the barrier height decreased significantly from 0.87 to 0.78 eV when the Conducting polymer-metal Schottky diodes show an interesting mechanical energy-to-electricity conversion ability to generate direct current (DC) power without rectification. However, little is reported about how dopants in conducting polymer affect the energy conversion behavior of Schottky diodes. In this study, a novel effect of dopants on mechanical energy-to-DC electricity conversion of conducting polymer-metal Schottky devices is demonstrated. Using polyaniline (PANI) as a model, conducting polymers doped with a series of protonic acids is prepared. Without dopant, the dev...
