Do you know of any material that can moderate the level of moisture of its local environment?
Example: if the desired moisture level is 30% and the local environment of the material is at 6% the material should extract moisture to achieve 30% moisture. If local environment is at 60% the material should retract.
The only material that I know of with properties similar to that, is zeolite. Do you happen to know any other of if zeolite can be used to maintain a certain level of moisture?
Thank you very much.
