is there any way we can increase the Low surface energy of plasticized PVC sheets by applying a chemical or by any mechanical modification either of which resources can be available easily for lab scale work.

I have read a few solutions such as i)degreasing using a solvent so the plasticizer is removed and the surface becomes more rougher and no migration of plasticizer would occur or ii)sanding of the sheet etc. but not too sure if they work.

I would prefer if any chemically modifications are possible. Thank you!
