What affects the rate of evaporation in a material?

Click For Summary
SUMMARY

The discussion centers on the factors affecting the evaporation rate of hygroscopic materials. Key points include the significant role of surface area in enhancing evaporation speed in both humid and dry conditions. Participants explored the possibility of engineering materials that can absorb moisture in high humidity and release it rapidly when humidity decreases. Specific materials were not identified, but the concept of manipulating surface area was emphasized as a critical factor in controlling evaporation rates.

PREREQUISITES

Hello!

I've been researching hygroscopic materials and evaporation rate a bit lately, and a question has struck me which I haven't found an answer to yet: What material factors affect the rate of evaporation? Is it possible to engineer a material which is hygroscopic (absorbs water) in humid air, but dries really quickly once the air humidity is lowered?

In general, a large surface area speeds up both directions. No idea about specific materials.
