Electro-Polymerization of Pyrrole

Organizations like the U.S. Environmental Protection Agency rely on field sensors that can detect traces of anionic water-soluble pollutants, like arsenate, chromate, perchlorate and pertechnetate. At PNNL, scientists are experimenting with modified polymer films that can recognize—and therefore be used—to detect pollutants. These polymers could potentially be incorporated into devices that would make detection rapid and economic. Shown here is a microscopic image of a polymer film generated through electro-polymerization of pyrrole from a water solution. PNNL researchers Dev Chatterjee, Thao Bui and Sam Bryan are working on this project.
