"... creating 2D polymers is tough. If just one of the holes in the growing mesh closes up in the wrong way, the membrane could buckle into a 3D mess. Polymer chemist Dieter Schlüter of the Swiss Federal Institute of Technology in Zurich worked on this problem for more than a decade before achieving success in 2014."

"Schlüter admits that he has faced scepticism about whether 2D polymers will flourish. "But that's healthy," he says. "And I'm very stubborn – I will not give up, I'm convinced of the great potential this development has."
