Scalable Manufacturing Process Spools Out Strips of Graphene
MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene. The custom-built, roll-to-roll chemical vapor deposition (CVD) system makes graphene on copper foil at 1,000°C. The results, published in ACS, are the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules, including salts, proteins, or nanoparticles. These membranes should be useful for desalination, biological separation, and other applications.
