I'm starting to play around with electrowetting (specifically the OpenDrop)
and I'm having trouble finding a source for extruded ETFE film of a
thickness of at most 50 micrometer.
Any ideas?
Anyone have experience with ultra hydrophobic coatings or spin coating?

i have a device which is a motorized vacuum-backed surface which you can use
for spin-coating. you place the item with its center of gravity on the axis
and then pull a vacuum, and then you can power the motor and spin the thing to
do spin-coating. It was originally for orienting silicon wafers so it's
enclosed in a stainless steel housing so it can be cleaned easily.

Very useful! How many RPMs?

i don't remember but it's a pretty powerful motor, so probably as many as you
want. it's a heavy-duty assembly, the hollow shaft to the vacuum plate has its
own pair of bearings supporting it, independant of the motor itself. So i
think the vacuum grip to your board (and properly centering it on the center of
mass) is your limiting factor in spinning it fast.

New subject: [CCLmembers] Sourcing <= 50 micrometer ETFE film
No but I’m psyched to research stuff with you since you’re thinking about
stuff in material science ;)
