Overview of Six Advantages of Electrostatic Flocking
Published Date
Although traditionally applied in decorative fields, electrostatic flocking technology has gained prominence in recent years across multiple domains—including sensors, tissue engineering, evaporators, and thermal management—owing to its exceptional capability for straightforwardly constructing vertical array structures. By electrostatically attaching high-aspect-ratio fibers to substrates, this technique enables large-scale control over fiber orientation, thereby forming porous or hair-like structures. Its advantages are significant: it not only enhances micro-force detection sensitivity but also offers multiple benefits such as large specific surface area, improved reflection/absorption properties, increased surface roughness, anisotropic structures, and reinforced mechanical performance.

While challenges remain in achieving highly customized pattern for functional materials, electrostatic f locking holds promise in replicating natural fluffy structures, such as villi and cilia, which could lead to superior performance in biomimetic and functional applications. Despite recent significant progress, a comprehensive review on this technology for cutting-edge applications is still lacking. This review aims to provide an in-depth analysis of electrostatic flocking’s broader applications and investigates the potential future of electrostatic flocking at the forefront of functional materials by examining the relationship between structure and per formance in advanced materials.
