Abstract

A polymer comprising one or more chalcogenide elements and one or more crosslinking moieties. The crosslinking moieties may be organic, inorganic, or both. Also disclosed is the related method for making a polymer comprising purifying a chalcogenide polymer powder comprising one or more chalcogenide elements, melting the purified chalcogenide polymer powder, adding one or more crosslinking moieties to the melted chalcogenide polymer, and curing the modified chalcogenide polymer at a temperature between 150 and 200° C.
