Does PEDOT:PSS need any "relaxation time" after drying or annealing?

During my tests I have observed that even after cooling to room temperature after annealing, the characteristics of the thin film (conductivity etc.) seem to be in flux. They only stabilize around...

Is there any way to completely coat silicon nanopillars in PEDOT:PSS?

I have been trying to spin coat PEDOT:PSS onto a nano-textured silicon surface (nanopillars of 70 nm height). I'm using a water based dispersion and I always end up with the PEDOT:PSS layer...
