Hi Abdul,

If you want your PDMS to stick on the ITO simply activate the surface of the PDMS and the ITO with UV-ozone treatment for 10-15 min. The adhesion is pretty strong.

Hi Abdul, I will go with Dilek on this one. Treating with short chain amino silane (from a dilute solution in ethanol or methanol) to create a monolayer is also an option. Upon coating with thin silanes, the change in electrical properties and resistivity is negligible. Best, Palash.

Thanks a lot everyone. I appreciate your help. I will try the UV ozone treatment and see how it goes first. Thanks again.

Hello,

we are also currently working on bonding PDMS to ITO coated glass slides. We have already developed a PDMS-PDMS or PDMS-glass bonding in a o2-plasma cleaner. However, using the same parameters (30W at 30-60s) when dealing with ITO and PDMS does not deliver a bond.

Does anyone have a recipe for bonding PDMS to ITO coated surfaces using a plasma cleaner. Unfortunatly, we dont have a Ozone chamber.

Kind regards,

Karl

I also suggest using silanes. Very thin layers can be achieved using straightforward vapour phase deposition, e.g. after plasma activation. You find the procedure within our publications.
