A strategy to achieve enhanced electromagnetic interference shielding at ultra-low concentration of multiwall carbon nanotubes in PαMSAN/PMMA blends in the presence of a random copolymer PS-r-PMMA

Mediated by the PS-r-PMMA, the MWNTs were mostly localized at the interface and bridged the PMMA droplets. This strategy led to enhance EMI shielding effectiveness at 0.25 wt% MWNTs through multiple scattering from MWNT covered droplets.
