Abstract
The purpose of this study is to prepare graphene nano sheets from graphite flakes and to improve the properties of the ionomer glass cement by adding different volume fractions of graphene, as the graphene was prepared using the planetary wet ball milling method as a basic method in addition to the use of both ultrasound and centrifugation as assistants. the prepared materials were characterized using various techniques such as (scanning electron microscopy, Raman spectroscopy, XRD) and others.
The results proved the success of the method used to convert graphite into graphene, in addition to improving the properties of the nanocomposite (glass ionomer cement + graphene), specifically at the volume fraction of 0.2% graphene.
