Abstract

Since graphene was synthesized in 2004, it has been widely used in electrochemical energy storagedevices and a number of other applications. This study aims to determine the effect of concentration and size ofMg metal particles on the structure, morphology, and electrical conductivity of Mg/Graphene nano sheets(GNS). This research is a laboratory experiment and descriptive research. GNS was synthesized by using amodified Hummers’ method. Mg 10, 20, 30 and 40 weight % /GNS were synthesized by using impregnationmethod using Mg salt (MgCl2.6H2O) as the precursor. Characterizations carried out on each material usingXRD (2θ = 26,768° – 26,938° for C(002) GNS and 2θ = 44,669° – 44,686° for Mg (102)), SEM-EDX and Conductometer proved that the graphene surface is able to reduce Mg2+ metal ions to Mg0 and to control the size and distribution of Mg metal particles deposited on the surface of the graphene sheets. Meanwhile, Mg metal particles that have been deposited are able to inhibit the agglomeration and re-stacking of graphene sheets so that it can increase the electron mobility and electrical conductivity of graphene
