In the past 10 years, the progression on research and development of graphene incorporated steel matrix composites
has attracted enormous attention of scientists and industries aiming to combine the advantages of each component producing
multifunctional materials with exceptional properties. Due to its unique properties, graphene is strong candidate for reinforcing
and decorating the structure of steel matrix and high expectations have been placed on it for various technological applications.
Recently, numerous studies directed toward on composites of graphene with steel particles. The interactions between graphene
and steel, either noble or non-noble steels, have enhanced durability, chemical, mechanical, thermal, and electrical properties to
a large extent. Herein, this paper addresses the most recent progress on graphene-based steel composites, their properties and
the applications.

Graphene materials have attracted enormous academics and industries to explore due to its outstanding
thermal and mechanical properties. In this work, the solution-casted polyvinyl alcohol (PVA) film reinforced
with shear exfoliated graphene and its properties such as hardness and mechanical behaviour were studied.
The compatibility between graphene and PVA was enhanced by the functionalization of graphene with gum
Arabic. The decoration of OH groups on graphene allowed better interfacial interactions with PVA through
H-bonding chains. As been observed during morphological study by scanning electron microscopy (SEM)
and x-ray diffraction (XRD), agglomeration of graphene sheets was detected at highest graphene loading
(0.15 wt.%). Improvement of mechanical properties was observed by nanoindentation for sample with
lowest graphene contents (0.05 wt.%). The enhancement of nanoindentation modulus sample was
contributed by homogenously distributed graphene in the matrix of PVA.
