Inventors: Tianqi Pan: Percy Calvo Marzal: Lisa Mauck Weiland: David H. Waldeck: William W. Clark: Tara Y. Meyer: David M. Brienza Ph.D.: Mary Jo Geyer

Patent Number: 15/368,254

Abstract

A material having a first non-zero elastic modulus capable of reversibly changing the first non-zero elastic modulus to a second non-zero elastic modulus in response to a redox reaction occurring in the material. A method of producing a material that is reversibly cyclable between a first non-zero elastic modulus and a second non-zero elastic modulus, comprising: preparing a polymer comprising both crosslinks that do not depend on metal binding and functional groups capable of having oxidation-state specific binding constants to a metal ion; and doping the polymer with a solution containing the metal ion.
