Surface Energy, Wetting & Interfacial Characterization

Surface energy, wetting, dispersion behavior, coating adhesion drivers, surface/interfacial tension, dynamic contact angle, and density characterization. Elect Nano uses this capability as part of application-driven materials programs where test setup, sample format, and data interpretation need to match the end-use requirement.
