Abstract: The present disclosure relates to a polymeric blend composite comprising Poly Ether Ketone/Poly-(2,5-Benzimidazole) containing pre-treated multi walled carbon nanotubes (MWCNTs) between 0.5 to 5 wt % were melt processed on a twin-screw extruder and granules so obtained were injection molded to determine heat deflection temperature (HDT) of these composites and storage modulus using DMA. It was found that HDT and storage Modulus for so produced reinforced blends were unexpectedly extremely high as compared to PEK/ABPBI blends without MWCNTs.

Abstract: A polymeric blend composite is provided which includes 60 wt % to 99 wt % Poly Ether Ketone Ketone (PEKK), 1 wt % to 6 wt % Multi walled carbon nanotubes (MWCNTs), and 0 wt % to 40 wt % Poly-(2,5-Benzimidazole) (ABPBI). A process for preparing the polymeric blend composite is also provided according to which 60 wt % to 99 wt % PEKK, 1 wt % to 6 wt % MWCNT and 0 wt % to 40 wt % ABPBI are mixed, followed by melt processing on a twin-screw extruder. The extrudates of the polymeric blend composite possess higher electrical conductivity and storage Modulus as compared to PEKK without MWCNTs and PEKK+ABPBI blends without MWCNTs.
