Wear-resistance triboelectric nanogenerator based on metal-organic framework modified short carbon fiber reinforced polyphenylene sulfide

Abstract

In aerospace, automobile transportation, disaster warning and other fields, triboelectric nanogenerators (TENGs) are a new type of energy harvesting device that converts mechanical energy into electrical energy. It is especially suitable for monitoring and early warning systems in harsh environments. This paper reported a TENG based on composites reinforced polyphenylene sulfide (PPS) by the metal–organic frameworks (MOFs) are constructed on the surface of short carbon fibers (SCF). The friction properties of the composites were investigated by using two different friction methods. The composites demonstrated excellent wear resistance, with reduced wear rates to 8.16 × 10^-7 mm³/Nm and 2.512 × 10^-7 mm³/Nm, respectively. Additionally, it exhibited outstanding high-temperature stability (445.9 °C). Therefore, the study highlights the potential of TENGs to serve as a sustainable solution for real-time environmental monitoring, paving the way for the development of robust and energy-efficient systems in harsh environment applications
