2026-09-29 Boosting tribovoltaic output and stability via synergistic protonation and coordination effects doi:10.57760/sciencedb.013z0 en The crystal structure and functional groups of the samples were characterized by X-ray diffraction (Rigaku Smart Lab 9 kW, Japan Neo-Confucianism Co., Ltd.) and Fourier transform infrared spectroscopy (Nicolet iS20, Thermo Fisher Scientific). Morphological analysis was conducted using scanning electron microscopy (Sigma 360, ZEISS, Germany). The optical absorption properties and band gaps were evaluated by ultraviolet-visible spectroscopy (UV-2700i, Shimadzu). The current-voltage (I-V) curves were measured with an electrochemical workstation (CHI760F, Shanghai Chenhua). The electrical resistance and conductivity of the samples were determined using a four-probe resistivity tester (Model FT-341, Ningbo Rooko). Mechanical energy input was applied via a linear motor test system (LPS1, MitraStar). The electrical output of all samples was recorded with a digital oscilloscope (MSO5354, RIGOL) and an electrometer (Model 6514, Keithley). The oscilloscope's sampling rate was set to 50 kSa/s. Instructions related to the reading of the oscilloscope can be found in the "Analog Outputs" section on page 153 of the Model 6514 System Electrometer Instruction Manual PDF.
