I'm completely new to polimer etching. I'm searching for something to
etch a polymer (PMMA) optical fibre (POF). I have to remove the
cladding, that is a 20 micrometer layer coating the fibre.
I'm thinking about using toluene, that is used to remove the polymer
jaket of silica fibre. The problem is that the fibre in use is all
made in PMMA, so that the etching must be an exposure time-etching.
Thanks a lot
Yes, I want to remove the cladding. It should be made of fluorine
polymers, while the core is in PMMA. I assumed is not possible to find
something that etches only the cladding... Right??
PDMS doesn't dissolve quickly, regardless of the solvent, but it will
go into heptane. The PMMA should be fine, but the density of heptane
(and other alkanes) is low, ~ 0.7.
Completely deuterated heptane is available with a density of 0.8 ;)
