Question

What makes teflon non stick ?

Answer 1

you mean as in pans and stuffs?

Answer 2

that's easy, because teflon is a non-polar substance, it doesn't stick to anything

Answer 3

it has a really weak IMF force, and because the teflon polymers are already saturated (it has attained the maximum total number of bonds) it can't really cross-link with anything, so there's no chance of it sticking to anything

Answer 4

do u know what teflong made up of its polymer and :) u should check its hydrophobicity and hydrophillic property :)

Answer 5

Teflon is made out of tetrafluoroethene,(polymerisation), this means it can be be able to make vanderwaal forces due to presence of electrons in the fluorine atom, but why doesnt substance stick

Answer 6

just read my explanation

Answer 7

The C-F bond is not very polarisable which means the electrons won't move sufficiently towards a hydrogen from water (or anything else) to form hydrogen bonds (or van der Waal's forces). This accounts for its non-stick properties.

Answer 8

but if you consider an atom of fluorine in the structure, it can have 6 pair of electron, which can induce permanent dipole towards any other molecules, :/

Answer 9

Wikipedia:
Fluorine has the lowest polarizability of all atoms: 0.56 10−24 cm3.[1] This causes very weak dispersion forces between polyfluorinated molecules and is the reason for the often-observed boiling point reduction on fluorination as well as for the simultaneous hydrophobicity and lipophobicity of polyfluorinated compounds whereas other perhalogenated compounds are more lipophilic.

Answer 10

If you would like to read this: (Although I didn't understand half of it) :P Seems like this is a rather controversial topic. xP

oh ok :) thanks
