New Guide: Contact Angle Measurement

Posted on Fri, Sep 29, 2017 by Ashley Wong

Contact angle measurements are vital in a range of research activities where it is important to know how well a liquid spreads over a surface. It is valuable information when either formulating solutions to  improve their wetting ability, or modifying surfaces to change their surface energy.

Whether you are new to the measurement or want to know more about how it can help your research, we have written a detailed written guide on the theory and techniques for contact angle measurement.

Contact Angle


This guide gives a summary of the background theories of surface tension and balanced forces that determine the contact angle.

Furthermore, there is an explanation of how to carry out practical measurement of a contact angle. This includes an overview of image capture, and how to measure the resulting contact angle of the image by using the polynomial fit method.
