Homework Statement
Why is Teflon oliophobic?
Homework Equations
N/A
The Attempt at a Solution
Teflon is a polymere of the tetra fluoro ethylene.
The molecule it's self is completly unpolar, but the bonds are majorly polar with an electronegativity diffrence of 1.5 resulting in a very stong bond requiring 560kJ/mol to disociate.
This is a picture of Teflon by the way, the more greenish centeral atoms are carbon, the outer lighter greenish ones are fluorine.
Seeing as the molecule has no polarity, you would think that it should disolve in oil, however it doesn't, why?
The only reason I can think of is because the molecule is so big that not enough oil can surround it.
