Abstract

This work examines possible correlation between electromagnetic shielding efficiency and resistivity of thermoplastic polymer nanocomposites with carbon nanotubes. Polyoxymethylen was used as basic matrix to which nanoparticles in the weight percentage ratio were added. Multi-walled carbon nanotubes in various percentages by weight ratio were used as filler. The nanocomposite was made by the Arburg injection molding machine. For evaluation of electrical properties electromagnetic shielding effectiveness and resistivity of the final nanocomposite with and without nanofillers was evaluated. These results are compared and discussed. Correlation between electromagnetic shielding efficiency and resistivity of thermoplastic polymer nanocomposite is evaluated and prediction model is introduced in the conclusion.
