How a material coats a surface, or sprays out of a nozzle is intimately linked to its interfacial tension and the surface energy of the materials. We can measure these properties using:
CPG has the ability to determine surface tension and contact angles on almost any surface configuration, including curved surfaces and fibers. We make use of home-built sessile drop analysis using Labview image analysis or a DCAT 15 dynamic contact angle analyzer that allows us to determine either advancing or receding contact angles or surface tensions.
