Hello all,
For the past week I have been working on a new electrode, the process however uses a double solvent cast in the construction of the electrode.
Initially a layer of CNT + Nafion in isopropanol are cast and dried at 100 degrees centigrade for 30 mins, this is followed by a cast of a mediator suspended in pure DMF.
Regardless of DMF having greater miscible properties than isopropanol, I'm curious if there is potential for the DMF to lift the first layer into the solvent?
Any advice will be greatly appreciated.
If the Nafion is soluble in DMF (and I think that it is soluble) than most likely you will either dissolve the CNT/Nafion layer underneath or erode its the surface.
you will need electrodes that are resistant to organic solvents -
