For cooling in phones, phase change materials, such as waxes and fatty acids are used for absorbing heat produced by devices when they melt. However, the total amount of energy exchanged during the solid-liquid transition is relatively low. Researchers in China found MOFs were the most promising for absorbing moisture from the air and release water vapor when heated as they can store a large amount of water and thus take away more heat when heated. They found that MIL-101Cr coating was able to delay the temperature rise of the sheets, and the effect increased with coating thickness. While an uncoated sheet reached 60°C after 5.2 minutes, the thinnest coating doubled the time and didn’t reach the same temperature until 11.7 minutes. The sheet with the thickest coating reached 60°C after 19.35 minutes of heating…read more. Open Access TECHNICAL ARTICLE
