I am preparing electrospun nanofiber samples for mechanical analysis. The meshes are collected on Aluminum foil, and it is so difficult to detach them from it to proceed the analysis.
I have done many trials using adhesive tapes but the scaffolds didn't detach well from the Al foil. Moreover, I tried to hydrate the samples with physiological solution, waiting to dehydrate and then taking them off from Al foil, but also this technique didn't work because once the scaffold become dehydrated, it attached to the Al foil making its collection difficult.
Please can anyone give me any suggestion to solve this problem??
I would like to mention that I have 2 different types of scaffolds (randomly oriented and highly aligned fibers)
Thank you in advance
Did you try spraying the Alu foil with a lubricant or hydrophobic coating prior to electrospinning? I have been using this trick successfully in the past. Unfortunately, I don't remember brand and name of the spray.
Besides, often one side of the Alu foil is smoother than the other.
I hope this helps,
Matteo
Hello Mohammad.
In the past I have done some electrospinning on aluminium foil. To collect some samples I put thin glass coverslips on top which allowed me the collection of the sample (with the aid of a scalpel).
Also, you can try with some teflon tape on top of the aluminium foil, which should detach easily.
Hope it helps,
Hector
Thanks Matteo D'Este for this recommendation, I will try to spray the aluminum foil with some lubricant before starting the electrospinning. Thank you again.
Dear @Hector Capella
Thank you for this suggestion. The problem is that I am working with rotating collector, so I can not place glass coverslips on the aluminum foils so I would prefer to use the teflon tape or the lubricant.
thank you again.
