Polymer membranes with molecular-sized channels that assemble themselves
Many futurists envision a world in which polymer membranes with molecular-sized channels are used to capture carbon, produce solar-based fuels, or desalinate seawater, among many other functions. This will require methods by which such membranes can be readily fabricated in bulk quantities. A technique representing a significant first step down that road has now been successfully demonstrated. Berkeley Lab and UC Berkeley researchers — led by materials scientist Ting Xu — have developed a solution-based method for inducing the self-assembly of flexible polymer membranes with highly aligned subnanometer channels.
