The complex regulation of droplet dynamics, based on the application of external electric fields and micro/nano functional surfaces, has garnered widespread attention in fields such as enhanced oil-water separation, self-cleaning systems, and novel imaging technologies. In this study, a PLE surface (composite biomimetic hydrophobic surface with micron-level honeycomb texture and nanoscale villi) was fabricated. Using a high-speed microscopy system, the detachment and movement of droplets on the biomimetic surface under a direct current electric field were experimentally investigated. By introducing a biomimetic surface correction factor, (ξ), a polarization and force model for droplets on the PLE surface was established. The results indicate that the amount of polarized charge (
