Abstract The droplet triboelectric nanogenerator (D‐TENG) harnesses energy from natural water droplets, though its performance and lifespan can be compromised by contamination on the functional layer. Water molecules have a strong affinity for polymer surfaces, which increases surface tension sliding‐off angle, leading to greater adhesion. As these droplets evaporate, they leave behind residues, such as calcium (Ca) magnesium (Mg) salts, that obscure surface, thereby diminishing electrification area altering dynamics—resulting in decreased electrical output. This study presents micro‐nanostructured D‐TENG with advanced anti‐fouling capabilities. By adding layer of metal nanoparticles followed ion etching fluorination grafting, retention accumulation are effectively minimized. demonstrates fourfold increase output compared predecessor. Following 10 000 interactions, original drops 53%, whereas variant only experiences 7% reduction. These enhancements provide significant insights applications contribute development strategies.
