Conductive polymers are plastic materials with high electrical conductivity that promise to revolutionize a wide range of products including TV displays, solar cells, and biomedical sensors. A team of McGill University researchers now reports how to visualize and study the process of energy transport along one single conductive polymer molecule at a time, a key step towards bringing these exciting new applications to market.
“We may easily study energy transport in a cable as thick as a hair, but imagine studying this process in a single polymer molecule, whose thickness is one-millionth of that!” said Dr. Gonzalo Cosa of McGill’s Department of Chemistry, lead researcher.
Working in collaboration with Dr. Isabelle Rouiller of McGill’s Department of Anatomy and Cell Biology, the team used state-of-the-art optical and electron microscopes and were able to entrap the polymer molecules into vesicles — tiny sacs smaller than a human body cell. The researchers visualized their ability to transport energy in various conformations.
“This research is novel because we are able to look at energy transport in individual polymer molecules rather than obtaining measurements arising from a collection of billions of them. It’s like looking at the characteristics of a single person rather than having to rely on census data for the entire world population,” Cosa explains.
