摘要

In this study, a sustainable triboelectric nanogenerator (TENG) was developed using biodegradable polylactic acid (PLA) and a non-biodegradable carbon fiber-reinforced PLA matrix (PLA-CF) fabricated via fused deposition modeling (FDM), coupled with a water-soluble polyvinyl alcohol (PVA) film prepared through the solvent casting method. The use of biodegradable and environmentally friendly polymer materials aims to address the ecological concerns associated with conventional non-biodegradable polymers used in TENG devices. Carbon fiber incorporation enhanced the triboelectric properties of PLA by improving its surface roughness, electron affinity, and mechanical strength. The fabricated materials were characterized using X-ray diffraction spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and water contact angle measurements. Mechanical strength was evaluated using a universal testing machine. The assembled TENG, comprising PLA/PLA-CF as the negative triboelectric layer and PVA as the positive triboelectric layer, demonstrated stable voltage output capable of lighting LEDs and functioning as a self-powered touch-counting sensor. This work highlights the potential of FDM-based polymer composites for efficient energy harvesting and interactive sensing applications.
