Influence of Surface Roughness and Surface Functional Groups on Surface Energy Hysteresis
The surface energy of materials is often characterized by contact angle measurements using probe liquids of known properties. These types of measurements are challenging to interpret on paper which has a irregular surface roughness and also displays capillary forces.
This thesis work will use paper of different surface roughness and different amount of functional groups to show the influence on contact angle hysteresis.
Program in chemical engineering or related topics.
Start: Spring term 2007 (early). 20 credit points.
