Abstract: Abstract In this work, a novel interpenetrating system including amorphous polystyrene/polyurethane and multiwall carbon nanotubes (PS/PU-MWCNTs) was in-situ constructed by the homogeneous bulk polymerization. The ultralow percolation threshold (about 0.01 wt%) and high electrical conductivity were… read more here.
