In Biointerphases, researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane. The technology is greater than 99% effective at separating a petroleum ether-in-water emulsion.
