The Impact of Hydrophobic Coating on the Performance of Carbon Nanotube Bucky-Paper Membranes in Membrane Distillation

By Ludovic Dumee, Jos L Campbell, Kallista Sears, Jurg Schutz, Niall Finn, Mikel Duke and Stephen R Gray


PTFE coated carbon nanotube BPs were processed and tested as potential membranes in DCMD. They exhibited improved properties compared to both their untreated counter parts and to commercial membranes. The difference was attributed to the higher hydrophobicity of the smooth surface and to an increased porosity compared to the PTTE membranes making of those membranes very promising structures for use as separation means in membrane distillation
