Abstract
This review addresses state‐of‐the‐art of wettability measurements for plasma‐modified, three‐dimensional (3D), porous, polymeric materials. Inherent challenges associated with evaluating wettability of these complex constructs are discussed, including expanding techniques from 2D to 3D substrates and collection of both static and dynamic contact angle (CA) data. Dynamic data include advancing and receding CA measurements, as well as changes in CA as a function of time. Limitations in analysis and interpretation of wettability data are highlighted to best represent wetting characteristics of plasma‐treated porous materials, as is the importance of placing wettability data in context with simultaneous surface chemistry and roughness assessment. A list of best practices recommendations is provided.
