Smart filter

Graphene, often hailed as a wonder material, is proving its mettle once again with the development by an international team of a smart membrane that can desalinate brackish water. The membrane performs better than current membrane coatings and could provide clean water solutions in a wide variety of situations where drinking water is inaccessible. “Our dream is to create a smart membrane that combines high flow rates, high efficiency, long lifetime, self-healing and eliminates bio and inorganic fouling in order to provide clean water solutions for the many parts of the world where clean water is scarce,” explains team member Mauricio Terrones of Pennsylvania State University whose team worked with colleagues at Shinshu University, Japan.
