When a smooth clean aluminum disc is pulled out from distilled water at a constant and slow speed, water droplets formed on disc surface. The water droplet formation is due to the adhesive force between water and aluminum surface is stronger than the water molecules itself. What can I do to reduce or to eliminate water droplet formation on the aluminum surface?

Move the disc faster
Cover the disc with something that water adheres to less
Spin the disc
Heat the disc to evaporate the water
Absorb the water (Wipe the disc as it is being removed)
Use gravity to help remove the water (Remove disc upside down)

try Rain-X. It's a product developed for car windshields that reduces the adhesive force between water and the surface. Frankly- I'm not sure how it works on aluminum- but it's worth a try.

I don't know enough on the subject.
Just curious about the condition.
1. Is the environment always cool and humid ?
2. Are you allowed to have hot/warm air blowing into the setup ? Or can you heat/warm up the alluminium disc?

We see water droplets on the outer floor of the glass through fact the water vapour latest in air on coming in touch with the chilly glass of water losses capacity and gets converted to liquid state which we see as water droplets.

Try an air jet (or 'air knife' as it's sometimes called) to blow the water off.
