The best thing to do would be to create an airgap by raising the level of the deck slightly between the two surfaces. In the event this just isn't possible I would suggest just sealing the concrete with a good sealer before applying the wood. Subsequent sealings will need to be done between the wood planks as needed. Plastics or Tyvec materials will trap moisture underneath themselves eventually causing a premature demise to the concrete. Maybe someone has a better solution I don't know about.
