More than just surface tension: the caveats in interpreting contact angles measured using surfactant solutions

This webinar features Dr. Shihong Lin, who explores the use of contact angle measurements as a tool in membrane research, with a particular focus on non-wetting requirements. Dr. Lin discusses the complexities and caveats of interpreting contact angles when using surfactant solutions, highlighting how these measurements can be misleading due to surfactant absorption on membrane surfaces. The session delves into the implications of these findings for membrane distillation and the development of omniphobic membranes, offering insights valuable for both fundamental research and practical applications in water treatment and desalination
