Khan Imran

Dear Udesh,

are you using PDMS Sylgard 184? The estimated interaction time? Furthermore, Is your PDMS planer film or structured ?

Udesh Dhawan

Hi Imran, unfortunately, at this moment of my research I'm not aware of the difference between sylgrad and the rest. However, the interaction with Phosphoric acid will particularly vary from 5 minutes to 12 hours. It will be the nanostructures Pdms which will be in contact with the Phosphoric acid.
