Researchers explore electroactive medical bioplastics


The U.S. Agriculture Department is funding a five-year project to develop electroactive polymers from natural, renewable feedstocks such as cornstarch.

The implications are significant because commercially available electroactive polymers made from fossil fuels,such as polyanaline, cost much more than corn starch (about 40 cents per pound in 50-pound bags). Polyaniline emeraldine-based polymers can cost thousands of dollars per pound.

A research team at the Plant Polymer Research Unit of the National Center for Agricultural Utilization Research operated by the federal Agricultural Research Service demonstrated the technical feasibility of making electroactive polymers from starch in a technical paper published in 2005....
