제목 Synthesis of graphene nanosheet/polyaniline composite in basic medium and its propreties.
초록 Recently the synthesis of graphene - polymer composite to improve the processibility of graphene has been reported. In the case of graphene nanosheet-polyaniline composite was synthesized in acidic medium (pH ~2) but poor dispersion stability was a problem to be solved. In this study graphene nanosheet-polyaniline composite was synthesized in basic medium (pH 9 ~ 11) based on Donnan effect. SEM and XRD was used to investigate the structure of the composite. Electrical conductivity and tensile strength was measured from free standing film made with the dispersion. Zeta potential was monitored to check the stability of the dispersion. Effect of pH value to the properties of graphene nanosheet-polyaniline composite will be discussed.
