I'm patterning a gold electrode array onto PDMS. A paper by Yongman Park [1] presents a method that gives good adhesion. You pattern the metal on glass and then stick it to a PDMS layer. The paper says to expose the PDMS to corona discharge. How do you do that? Why do you do that? Is it the same as exposing to oxygen plasma? The paper also says treat the metal on glass with 3-mereaptopropyltrimethoxysilane (3-MPTMS) in ethanol solution, but it doesn't say why. Why would you do that?
