ON/OFF Switchable Nanocomposite Membranes for Separations [PDF]

Polymers, 2020
Although water, air, and other resources are abundant on earth, they have been subjected to strict environmental regulations. This is because of their limitation of availability for human consumption. In the separation industry, the membrane system was introduced to increase the amount of resources available to mankind.
