Plastics made with thermally conductive fillers containing defects performed 160% better than those with perfect fillers

"overcomes low thermal conductivity leading to overheating, by incorporating highly thermally conductive fillers: metals, ceramics, diamond/ graphite oxide... perfect fillers on their own 5X more thermally conductive than imperfect ones, but polymers with graphite oxide fillers containing defects performed 160% better due to enhanced vibrational couplings between polymers/ defective fillers at polymer/filler interfaces... high-performance microchips, soft robotics: cooler/ more efficient through improved heat dissipation"
