HSMG®

High Strength Metallurgical Graphene® is a large-area polycrystalline graphene sheet, manufactured with a metallurgical method based on graphene liquid phase growth. HSMG® is crystallized on a liquid metal surface which allows each graphene particle to rotate and rearrange until fitting perfectly into the crystallizing graphene sheet. Thereby HSMG® has little to no imperfections.

BRAND NEW GRAPHENE

NEW PRODUCTION METHOD

HSMG® is a product which originated from a unique production method which allowed to manufacture graphene on a liquid metal matrix. The method was designed by the scientists of Materials Science and Engineering (Lodz University of Technology) and developed into a highly efficient production process together with AGP.

HSMG IS THE NEW GRAPHENE

In comparison to the most widespread CVD graphene, HSMG® is much stronger and durable. High Strength Metallurgical Graphene® can be also produced in large quantities in short time which finally allows to use graphene on an industrial scale and is available in a large variety of sizes: from 10 x 10 mm up to 200 x 90 mm. Just like the theoretical one, this type of graphene shows semiconductive qualities.

MAIN PROPERTIES OF HSMG®

HSMG®, due to its unique qualities, is suitable for a large variety of applications - energetics, electronics, composites, filtration membranes, car industry, aviation, space industry etc.

  • Monocrystalline flakes up to 1 mm
  • In tensile tests elongation 100 %
  • Single and multilayer sheets of any size
  • Very high coverage and continuity (min 95 %)
  • Easily transferable onto various substrates
  • Stability without a substrate
  • Stable negative thermal coefficient of electroconductivity
  • Stable mechanical and physical properties under thermal fatigue conditions
HSMG® production is based on formation of graphene on liquid metal. Liquid is the flattest possible surface and using it as a matrix allows each graphene particle is able to rotate and rearrange until fitting perfectly into the crystallizing graphene sheet. This way the resulting graphene structure has little to no imperfections.
Additional advantage of this method is zone cleaning effect (e.g. pushing the contaminations outside of graphene flakes) which allows elimination of impurities on the production level.
The method was design by the scientists from Material Science and Engineering (Lodz University of Technology) and developed into a highly efficient process together with AGP.
