All of those rely on condensation, which is caused by temperature getting low enough the air can’t hold water. The mechanism for the new material is completely different. It doesn’t appear to require the air to be saturated. We already have substances that remove water from air. In those the water becomes absorbed. This seems to work on a similar principle. The real difference is the water doesn’t stay absorbed.
