Surfaces decorated with fiber arrays are ubiquitous in the natural world because they can provide functions such as sensing (hair cells), wetting (lotus leaf), and adhesion (gecko foot). However, recreation of these functions in synthetic materials is challenging due to multiscale engineering processes to control properties of individual fibers and their arrays. Here, we introduce chemical vapor deposition can be performed on surfaces coated with liquid crystal films to synthesize end-attached nanofibers.* The approach enables access to nanofiber arrays with controlled size, shape, and organization via self-assembly of monomers mediated by elasticity of liquid crystal template.* We also demonstrate the nanofiber arrays to permit tailoring of a wide range of functionalities, including wetting, conductivity, and adhesion. Our recent discovery for these various lines of investigation will be also discussed. * Y.-K. Kim, et. Al., NATURE, 557, 539 (2018); SCIENCE, 362, 804 (2018)
