多孔结构如何提高材料的氧气通透性
Hydrogels contain a great deal of water, which makes them soft and useful for contact with living tissue. Yet water-rich materials can make it difficult for gases such as oxygen to move through them.
Researchers created a gel with a stable network of tiny air spaces. Silica aerogel beads helped the structure keep those spaces from collapsing.
