Nagoya Institute of Technology reports an order of magnitude reduction in thermal conductivity for polyurethane films via incorporation of hollow-sphere silica nanoparticles

On March 3, researchers from Nagoya Institute of Technology and Grandex Inc. reported in Advanced Power Technology that incorporation of hollow silica nanoparticles (HSNPs) resulted in a reduction in thermal conductivity from 0.3 W/m.K to 0.03 W/m.K for a 25 µm polyurethane film. Besides the stra...
