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.
