New polymers lead to lower costs and higher performance, scientists say.
Superconductors made of organic polymers such as plastics promise to be inexpensive and easier to use than current superconductors, which are based on pure metals and ceramics, says Greene. Now that we have a successful experimental approach and initial success, we can begin the process of trying to understand what is required at the molecular scale to enhance the superconductivity. But getting there will mean overcoming some daunting physical and technological challenges, Greene says. Superconductors are materials that offer no resistance to electricity when cooled to extremely low temperatures. Once a current is produced in a superconductor, it flows with no measurable loss of energy and no heat generation.
