High strength metallurgical graphene (HSMG®): Prospects for application in functional laminates
and sensors
Piotr Kula and W Szymanski
Lodz University of Technology, Poland
Effective practical application of products made of graphene as the base material are contingent on the development of
methods of manufacturing large-area graphene on an industrial scale, the structure and properties of which would be
similar to theoretical ones. At the Lodz University of Technology, an original industrial method was developed of producing
large-area sheets of graphene through its controlled growth from metallic liquid phase. Graphene produced this way is close
to structural perfection, i.e. it is single-layered and quasimonocrystalline, which results in its very high cohesion confirmed
in static and cyclic tests of tensile strength. The authors of the 2D material produced in this manner called it "High Strength
Metallurgical Graphene"–HSMG®. Also disclosed were two alternative growth mechanisms of graphene from the liquid
metallic phase, i.e. dendritic and cellular, which produce HSMG with different electrical properties–respectively conductive
graphene (c-HSMG), and semiconductive graphene (sc-HSMG). The capabilities of HSMG® were indicated with respect to
selective adsorption and chemisorption of gases-in particular hydrogen-from gas mixtures. With the described mechanical and
physical properties, high strength metallurgical graphene is ideal for application as the reinforcing phase and at the same time
functionally active phase in laminates. HSMG can be repeatedly transferred between different substrates; this offers prospects
of supervised control over the distance between successive reinforcement layers in the polymer matrix. A separate area of
potential application of HSMG® is sensing of gases and electromagnetic radiation. The success of graphene as an engineering
material of the future depends on the creative creation of new generation devices, rather than on strenuous attempts we have
seen so far to replace other components with graphene in pre-existing design solutions and technologies.
Biography
P Kula, PhD, DSc, is the President of Polish Materials Society, a Member of European Materials Science Society (FEMS) and American Society for Metals. He has
been the Head of Materials Science and Engineering Institute at Lodz University of Technology since 1997. Since then, he has founded and developed a strong
research team in the field of Surface Engineering and Nanotechnology, recognized as the Lodz School. His main scientific and research achievements are non
steady state models of vacuum carburizing and vacuum nitriding, artificial intelligence based software that supports these processes on the industrial scale and
recently the manufacturing technology of high strength metallurgical graphene (HSMG) as well as the concept of using HSMG to produce the graphene-based
nanocomposite for reversible storage of hydrogen.
