Advances in materials science have been at the forefront of the materials revolution. Controlling the accumulation or rejection of certain types of materials at solid surfaces or liquid interfaces is very important for numerous applications, such as biocompatible surfaces, sensor technologies, cleaning processes as well as emulsion and foam stability. Adsorption of materials to solid surfaces is highly dependent on the interaction between the solid material as well as the adsorbate, while surface active agent properties largely influence the behavior and properties of liquid interfaces. New surface-modified materials are widely being employed to create products such as self-cleaning windows, disposable contact lenses, catheters, dental prosthetics and biocompatible implants. The performance of these materials (greatly) depends on their surface properties.
The speed of adsorption of surface active agents to liquid or solid interfaces plays a key role in formulations for industrial cleaning processes, as well as stabilization of emulsions and foams for paint, pharmaceutical, cosmetic, food and mineral processing applications. Attension provides a range of products for both dynamic and static contact angle measurements (Theta and Sigma series) for studying solid surface properties, as well as for dynamic and static surface/interfacial tension measurements (BPA, Theta and Sigma series) for liquid formulations containing surface active agents.
