Research Project Title: Superhydrophobic membranes for membrane distillation and crystallisation
Membrane distillation is a vapour pressure-driven technique where a hydrophobic membrane is used as a separation barrier between two fluid streams. Recent research has targeted the potential application of desalination and membrane crystallisation using membrane distillation systems. However, practical implementation of membrane distillation can be compromised by various factors, with membrane wetting being the biggest challenge. Superhydrophobic modifications of the membrane surface can be used to minimise the degree of wetting, allowing for longer operating times, but little is known about the performance of superhydrophobic membranes in membrane distillation.
This project therefore aims to:
1. Fabricate superhydrophobic membranes and examine the effects of surface structure on membrane distillation performance.
