The lecture
In this lecture Professor Ivan Parkin looks at the formation of self cleaning surfaces. These are surfaces that don’t get dirty to ones that can be used for cleaning up oil spills- through oil-water separation. The work focusses on superhydrophobic surfaces and shows how they can be made and used in a wide range of applications.
The lecture involves a number of demonstration including a superhydrophobic race track and the treatment of filter paper to make it completely un-wettable and the phenomena of water bouncing on highly water- repellent surfaces. Superhydrophilic surfaces (water loving) will also be covered including how to make commercial self cleaning glass.
This lecture is recommended for students Year 10-13 and their teachers and parents.
