There are contactless methods to measure sheet resistance, e.g.:

Hej!

We are experiencing same problems in our lab. If you can measure in liquid you can determine the impedance which will give you also the information about the resistance.

another option might be conductive AFM also.

Cheers!

But liquid will definitely swell the polymer film...thereby changing the conductivity
