I have as-spun PAN electrospun nanofiber mat prepared using electrospinning. For stabilization/carbonization, should I peel off that fiber mat from aluminum foil and keep in the furnace or I can keep the fiber mat with aluminum foil in the furnace in this case aluminum foil may get burn.
If I peel off the fiber mat and do the stabilization/carbonization in the furnace then I will require a binder material to coat that carbonized fiber material on steel foil so that I can use it as a working electrode in three-electrode cyclic voltamettey experiment.
In your paper you have not mentioned any binder material (Flexible all-fiber electrospun supercapacitor, 2018)
should I use any binder or is there another method which I can use.
Hi,
I am interested in this field, and I have the same question that you asked. Did you get answers?
Thank you in advance...@Sumit Dubal
I suggest you keep the electrospun nanofiber on the aluminum foil which in turn can withstand oven temperatures...try it I think it will work

If you apply a good heating program for carbonization and you have a full N2 atmosphere inside your furnace, you do not need a binder because you will get a coherent carbon mat this way. It is not good to keep the Al foil as Al melts at 660.3°C and you will need a higher temperature for good carbonization.
If you are exposing the sample to temperatures higher than what the Aluminium foil can withstand (like over its melting point ~660 C) then it may not be ideal.
Perhaps it would be better to try the heating with as-spun membranes. You can electrospin PAN onto the aluminum foil and then peel it off for the post-process. It might be tricky to remove it from the Al foil, so try to electrospin a thick layer of PAN so that it detaches from the foil substrate more readily.
