- Abstract
Surface wetting is a multiscale phenomenon where properties at the macroscale are determined by features at much smaller length scales, such as nanoscale surface topographies. Traditionally, the wetting of surfaces is quantified by the macroscopic contact angle that a liquid droplet makes, but this approach suffers from various limitations. In recent years, several techniques have been developed to address these shortcomings, ranging from direct measurements of pinning forces using cantilever-based force probes to atomic force microscopy methods. In this review, we will discuss how these new techniques allow for the probing of surface wetting properties in far greater detail. Advances in surface characterization techniques will improve our understanding of surface wetting and facilitate the design of functional surfaces and materials, including for antifogging and antifouling applications. Surface wetting describes the interaction between a solid surface and a liquid droplet, the dynamics of which govern the performance of functional surfaces for nanoscience and industrial applications. Here, the authors review how a combination of new surface characterization techniques allows the probing of surface wettability in greater detail compared to conventional methods (e.g., contact angle measurement).
