Electromagnetic and microwave absorbing properties of polyimide nanocomposites at elevated temperature

The effect of hybrid fillers (multi-walled carbon nanotubes (MWCNTs) and CB) content on the microwave absorbing performances of such composites has been addressed and also the high temperature absorbing properties were investigated. The results demonstrated the potential of using hybrid fillers filled into phenylethynyl-terminated polyimide matrix as absorbing coating with good high temperature absorbing properties.164
