Graphene Paper

Graphene paper is paper made from graphite oxide paper. The material is exception strong from inside due to its intrinsic stiffness and strength. This is due to the two dimensional graphene sheath or layer inside it. It is possible to process, reshape and reform. Graphene paper is made by milling or powdering raw graphite by processing, purifying and filtering it with nano-structured patterns or shapes. The graphene nanosheet produced stacks are single layer hexagonal carbon lattices and then placed in streamlined structures enabling it with mechanical, electrical and thermal properties. A synthesized technique and heating routine produces a material with a high flexibility, strength and toughness. When this is compared to steel, the paper is about six times lighter, five to six times lower in density, about two times harder and higher tensile strength with thirteenth bending or twisting firmness. Graphene paper is planned to be highly used in the automotive and aviation industries. Also, to be used to build lighter and stronger cars and passenger airplanes. This is due to the fact that such cars produce less pollution, use less fuel and such planes cheaper to run and environment friendly. Airplane companies such as Boeing and Delta Airlines have started using graphene paper instead of regular metal sheets with graphene paper or carbon fibres or carbon based paper. It is also put to use in the mining, material processing or manufacturing industries in Australia. The last two decades have seen the decreasing usage of metals with carbon based materials. This is due to the fact that steel based materials have increased in cost and do not produce or provide with the return on investment compared to carbon based products. Mines in Australia are rich in graphite based products. The new graphite material is extremely useful to the industries as they happen to be economical, made in the neighbourhood and have world class technological edge for mass production and industrial use. As graphene paper is stronger than diamond and lighter than most metals, it has the ability to change its electrical properties from insular to conductor and to semiconductor. It is also planned to be used in the production of batteries, fuel cells, super capacitors, electronic components and super thin chemical or nano filters. Aircraft fuselages are also built using graphene with polymers and metals. It may also be used in the future to build cars, planes and army body armor.
