This is probably not a very intelligent question. When cotton wool gets wet, it shrinks. Is it possible to wet it without shrinking? I know that it shrinks because the water surface tension pull cotton wool together.
These are some technique that I can think of
- Add surfactant? But this will contaminate water with surfactant.
-Deposition, opposite of freeze drying (sublimation)
Thank you.
