I am using Eco flex as a dielectric material for my flexible capacitive pressure sensor. To fabricate the second layer of my capacitive electrodes I need the plasma treatment on the surface of Eco Flex.
You need an access to a vacuum chamber with plasma creation system or a plasma gun. Some plasma guns are quite small and handy.
Usually if you work with a new material you need to conduct a few test runs , for example treat your substrate for 2s, 4s and 6s or similar and then apply your treatment and measure adhesive force.
What I've found in my research is that even a very short treatment time improves the adhesion very significantly.
Unless there is a specific reason to use oxygen plasma, you could also try with atmospheric plasma. I've found that atmospheric plasma promotes adhesion very well and removes the need for an oxygen tank (and lots of safety hazards associated with it).
Thank you Suliga, highly appreciate your answer. I am trying RIE O2 Plasma and hopefully it will work.
You should use UVO treatment or RIE O2 plasma (better) in several minutes. You can apply it for all case of elastomers.
Hi Tausif,
I am finding myself in the same position as you. Would you mind sharing how you ended up improving the ecoflex adhesion please?
Thank you!
