“…Moreover, the tensile test confirmed the substantially higher mechanical strength of sc-HSMG (more than three times higher strain at the conductivity loss) compared with CVD and c-HSMG. Therefore, sc-HSMG sheets seem to be a good candidate for further investigations as a functional nanomaterial for future efficient hydrogen storage systems [21], reinforcing sheets in composites [22], strain sensors [4], filtering membranes [23] and many others.

In this work, the growth mechanisms of chemical vapor deposited and metallurgical graphene and their selected mechanical and electrical properties were investigated. The study revealed the influence of the growth mechanisms on monoand poly-crystalline nanostructures of synthesized graphene monolayers. The structure of flake boundaries greatly affects both the mechanical and electrical properties. The key factors are overlapping of the graphene flakes, their degree of mismatch and the presence of π type bonds. all of these issues should be taken into account when developing industrially scaled technologies for graphene manufacturing.Keywords: graphene; growth mechanism; electrical properties W pracy przedstawiono wyniki badań mechanizmów wzrostu oraz wybranych właściwości mechanicznych i elektrycznych grafenu chemicznie osadzanego z fazy gazowej oraz grafenu metalurgicznego. badania wykazały wpływ mechanizmów wzrostu na mono-i polikrystaliczne nanostruktury syntetyzowanych monowarstw grafenu. Struktura granic płatków grafenu znacząco wpływa zarówno na właściwości mechaniczne jak i elektryczne. Kluczowymi czynnikami są: nakładanie się płatków grafenu, stopień ich niedopasowania oraz obecność wiązań typu π. Wszystkie te aspekty powinny być brane pod uwagę przy opracowywaniu technologii produkcji grafenu na skalę przemysłową.

It will have the ability to adsorb 37.3% of hydrogen at a pressure of 10 MPa and a temperature of 250 K [1].…”

Gas sorption conditions on the graphene surface, as well as their influence on graphene properties, play a significant role when applications are considered. The influence of temperature and pressure on electric properties of graphene were investigated and discussed within this work, which was conducted in order to determine the border values for the sorption and desorption process of hydrogen on the graphene surface. The temperature was changed within the range of 243-373 K. Two types of graphene were used for comparison: one of graphene synthesised by our own method using chemical vapour deposition (CVD) and one of high strength metallurgical graphene (HSMG) in both conducting (cHSMG) and semiconducting (scHSMG) varieties. The characteristics were determined under hydrogen atmosphere in a fitted apparatus under pressure. The overall target material relies on the hydrogen storage of a designed graphene-based composite [1,2].

“…The transfer technology is a likely problem in this case. One possible solution is the application of high strength metallurgical graphene (HSMG), characterised by high strength and a potential for effective transfer [22][23][24][25][26][27][28]. This original 2D material is grown on the surface of liquid copper in the form of quasimonocrystalline monolayer [22,23,28].…”

The main objective of the present study is an elaboration of a method for a transfer of high strength metallurgical graphene (HSMG) and its introduction into the structure of fibre laminates. In this work, two transfer procedures have been established: a transfer onto structural adhesive film (SAF) and a direct transfer onto two types of carbon fibre pre-impregnates (uniaxial and biaxial cloth). An important novelty of the presented experimental work is a use of scanning electron microscopy (SEM) operating in the absorbed electrons (AE) mode. This technique enables the evaluation of graphene continuity on a large area within a relatively short time. The SEM/AE technique made it possible to ascertain that the transferred graphene was characterised by a low level of defects, indicating that it could be used as a reinforcing phase in composites. Both transfer procedures, one onto SAF and the other directly onto the pre-impregnates were used for manufacturing flat laminates as well as tubular profiles. The flat samples, containing 0.68 ppm HSMG by weight, exhibited a 9% increase of low cycle fatigue strength. The tubular profiles (bicycle components) with approximately 0.22 ppm of HSMG exhibited a significant increase of fatigue wear during initial tests. In addition, no fatigue delamination was observed at interfaces between the pre-impregnates separated with HSMG graphene.
