Graphene is an allotrope of carbon, or, in other words, a flat structure of carbon atoms arranged in the form of a hexagonal lattice (like a honeycomb). This material is about 200 times harder than steel. This material is about 200 times harder than steel. At the same time, it has a much lower density – the mass of one square metre of graphene is only 0.763mg. The thickness of a graphene layer is equal to the thickness of one atom of carbon. The material’s properties are impressive. Graphene is an excellent conductor of heat and electricity. It is almost completely transparent. It is very lightweight and flexible. It may be stretched by up to 20% with respect to its length. It is impermeable to any chemical substances. any chemical substances. Research has shown that graphene also has antiseptic properties – it prevents the growth of pathogenic bacteria. Its structure and properties make it the most robust material in the world. Its unique properties make its application potential almost unlimited.
There are two main types of graphene: graphene flakes and single-crystal graphene sheets. Both of these are successfully manufactured by Advanced Graphene Products.
This graphene type is obtained from graphite precursor as a result of chemical synthesis or mechanical treatment that involves breaking down the graphite structure into individual graphene flakes. Graphene flakes occur in the form of dry powder, various types of liquid dispersions and pastes. It is used as an additive in paints, varnishes and composites – thus effectively improving the properties of the final product.
It is a large-area quasi-monocrystalline graphene sheet produced by metallurgical growth on liquid metal. The growth technology is patented and implemented for mass production by Advanced Graphene Products. The product features increased durability and a reduced number of defects. The size of single grains in the layer reaches up to 1mm, and the structure of graphene is continuous, as the growth process minimises the formation of the so-called ‘overlapping’. overlappingu. In practice, it means that long graphene ribbons can be obtained in the production process, which can be transferred to any material. Graphene manufactured with HSMG® technology also has semiconductor properties. The possible applications of this type of graphene are currently being explored in the aerospace sector, construction, electronics and sports equipment and in various kinds of sensors.
To date, several companies have attempted to produce graphene-based filament. However, due to the very limited availability of graphene and its high price, none of them managed to implement this product on a macro scale. As a global graphene producer, we have the ability to produce graphene-based filament on a mass scale. Our formulation is standardised, so we guarantee the highest and repeatable quality. PROGRAFEN PLA and PET-G filaments enriched with graphene flakes demonstrate significantly better mechanical properties than traditional plastics. Graphene-based filaments provide very high values both in terms of elasticity and tensile modulus. Graphene-based filament will prove useful whenever you need a resistant and durable – and at the same time – elastic and ductile material.
