New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes. They collaborated with Kenneth B.

Heat-conducting polymer cools hot electronic devices at 200 C; potential for automotive applications

Green Car Congress

A team led by researchers from Georgia Tech have used an electropolymerization process to produce aligned arrays of polymer nanofibers that function as a thermal interface material able to conduct heat 20 times better than the original polymer. This material could ultimately allow us to design electronic systems in different ways.
