Paper Abstract

Coatings with switchable surface topographies will open pathways to completely new coating functions. Very recently we use an AC electric field to actuate the surface topographical deformation of a fingerprint liquid crystal network. In this article, we present the leading parameters that influence the surface modulation amplitude, including cross-linking density, glass transition temperature Tg, the polarizability of liquid crystal monomers and fingerprint pitch. This investigation will help to optimize the modulation performance of the LCN coating to gain better integration into practical devices.
