plexiglas esl project

elvis85 · 15th September 2006, 10:52 PM

Hi I haw bean thinking of building an esl for some time now and figured out that i want to build on in plexiglas.

But what wories me is what I can use to get an conducting surface on the plexiglas while the plexiglas remains somewhat transparent. or if it is at all posibel.

I read an article about using graphite on the diaphrame but is that posible to use on the other conducting surface to?

thank you for reading.

Maybe if you posted on the ESL planar forum you might get more replies

You need high conductivity on the stator. Using graphite, you'll need a thick layer and that will not be transparent.

The best transparent conductor is ITO (indium-tin-oxide). It's not hard to put that on plastic with the right equipment, but CVD is beyond the reach of an amateur. You might look at getting ITO-coated polyester film, then laminate that to Plexiglas.
