Polymer runs cold

Polymers are usually good insulators. However, by harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers at Georgia Institute of Technology have developed a thermal interface material that can conduct heat twenty times more effectively than the original polymer. The modified material can reliably operate at temperatures of up to 200 degrees Celsius and could have applications as a component of electronic heat sinks for cooling computer chips, high-brightness LEDs and the internal circuitry of mobile devices.
