Graphite-Wrapped Nanofibers Catch More Water

Aug-28-18 A nanofiber net able to pull drinking water from the air could bring relief to drought-stricken areas.

Fog nets are an established way to collect water from the air, as water vapor condenses on the net’s fibers to send the liquid into collection bottles. To increase the efficiency of these nets, the team from the University of Akron created a nanofiber cloth based on an electrospinning process that sees nanoscale fibers wrapped around tiny bits of expanded graphite. Compared to “spaghetti around meatballs,” the fiber-wrapped graphite provides a large surface area for the droplets to condense on, and squeezing or heating the material will trigger the water to be released.
