A Comparative Study of Multiwalled Carbon Nanotube Based Polystyrene and Toughened Polycarbonate Nanocomposites- Juniper Publishers
Juniper Publishers - Academic Journal of Polymer Science Authored by Nisha Bagotia The main objective of this article is to describe the effect of different length (aspect ratio) of carbon nanotubes (CNTs) on the electrical conductivity and electromagnetic shielding effectiveness of polystyrene/l-MWCNT and toughened polycarbonate/s-MWCNT composites. Long and short MWCNTs having aspect ratio of ~666 - 1333 and ~157 respectively were used for melt-mixed with polystyrene and toughened polycarbonate in a micro compounder. The uniform dispersion of MWCNT in matrix was confirmed by scanning electron microscopy. The realization shielding effectiveness value of -21dB respectively for PS/l-MWCNT composites: and -27dB for TPC/s-MWCNT composites at 10phr loading of MWCNTs, which show their potential use in making of mechanically strong and light weight EMI shield used for commercial application.
