Paper Title:
Electromagnetic Interference Shielding and Mechanical Properties of Maleic Anhydride Functionalized MWNT and Poly (urea urethane) Nanocomposites
  Abstract

The functionalized multiwall carbon nanotubes (MWNTs) have been prepared by free radical reaction with maleic acid and maleic anhydride. The functionalized MWNT was further blended with poly(dimethylsiloxane) (PDMS) based Poly(urea-urethane) (PUU). Both maleic acid modified MWNT (Maa-g-MWNT) and maleic anhydride modified MWNT (Mah-g-MWNT) showed enhanced dispersion compared with that of pristine MWNT and PUU.For MWNT/PUU nanocomposites containing 5 phr functionalized MWNT, the maximum microwave absorption was -19.2 dB for Maa-g-MWNT/PUU nanocomposites and was -22 dB for Mah-g-MWNT/PUU nanocomposites.
