Abstract

Since graphene was synthesized in 2004, it has been widely used in electrochemical energy storage
devices and a number of other applications. This study aims to determine the effect of concentration and size of
Mg 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 a
modified Hummers’ method. Mg 10, 20, 30 and 40 weight % /GNS were synthesized by using impregnation
method using Mg salt (MgCl2.6H2O) as the precursor. Characterizations carried out on each material using
XRD (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
