| Summary: | This report provides an experimental investigation on the effect of wettability and the contrast of two different and parallel surfaces on a liquid droplet. The work includes a study of the relevant literature and development of an experimental setup to understand and demonstrate the behaviour of a deionised water droplet when introduced to two parallel surfaces. The surfaces would include different materials to alter the contact angles and contrasts. Liquid droplets will vary in sizes and temperatures are also to be varied when conducting the study.
The general experiment is recorded with a high-resolution camera at 2 Frames Per Second (FPS) to document the advancing, receding behaviours of wetting as well as to record the general phenomenon of either a transfer or bridging between the two parallel surfaces. These images will then be exported and analysed using ImageJ analysis software.
This study will compare and analyse three primary substrate types: hydrophilic, hydrophobic and superhydrophobic under various conditions such as varied temperature and droplet sizes. |
