In the present work novel nanocomposites have been prepared using sulfonated polystyrene-block-poly (ethylene-ran-butylene)-block-polystyrene (SPSPB) as matrix material. Two types of nanofiller were used i.e. neat graphite (G) and nanobifiller of graphite-polyoxometalate (G-POM). The series of SPSPB/G and SPSPB/G-POM nanocomposites were developed using simple solution method. The nanocomposites were incorporated with various filler content (0.01-0.5 wt. %). The SPSPB/G revealed flake-like

The tensile strength of sulfonated polystyrene-based matrix nanocomposites increased from 60.9 to 93.2 MPa with the nanobifiller addition of 0.01 to 0.5 wt. %. Thermal conductivity of SPSPB/G-POM 0.01-0.5 was higher (1.9-2.7 W/mK) than the SPSPB/G series. Higher electrical conductivity of 0.68 Scm -1 was also achieved with the 0.5 wt. % loading of G-POM.
