QUESTION:

Where can I get a little bit of Teflon?

 

 

ANSWER:

ÅngströmLink AL-2233 is basically that.  A Teflon-like polymer dissolved in an evaporative solvent.  To get a thin layer of ‘almost -Teflon’, make a thin layer of AL-2233 and let the solvent evaporate.

What will be left behind is an amorphous polymer layer that:

  • Can range in thickness from <10 nm to 10u thick (anti-reflective lens coating or cladding for a waveguide)
  • Has a Refractive index of 1.33 (matches water)
  • Is very hydrophobic (like Teflon, can be used to mask areas from other coatings or as an optical grade mold release)
  • Is optically clear (in such thin layers)

Fluorination is the thing that makes AL-2233 so much like Teflon.
