Abstract

In insitu microemulsion synthesis, we have synthesized successfully nanocomposite based on polystyrene (PS) and two-step reduced graphene oxide sheets with heat and NaBH4 agent after they had been treated by monoglyceride. Resulted Nanocomposite has been better in electrical conductivity (approximately 2,01 × 10-2S / cm), thermal stability (increased about 120 oC) and physical properties (glass transition temperatureincreasesof over 6.40 oC, elastic modulus increases by 45 %) than the pure PS properties.
