Can anyone suggest a suitable porous support for fluorinated polymers? I would like to cast a membrane on the support using phase inversion technique. Any suggestions will be appreciated....

Hi Zainab,
Solvent can be DMAc, DCM, THF,NMP, DMSO.
If you can recommend a type of support for a type of solvent it will be great.
I know that the compability depends on the surface tension of the solution but I will happy to know what is common for fluorinated polymers.
Thanks
Hi
common solvents like DMAc, DCM, THF,... can dissolve many polymers. so your support polymer cannot be a common polymer ( such as PES, PVDF, PVA, PI, PEBA,...).
my suggestion is to change the solvent of top layer polymer. you can use non-polar solvents (n-heptane) or aromatic polar solvents (toluene).
