A New Method for Making Graphene has an Awesome Application: A Space Elevator! universetoday storybywill
recently commenced operations, using the CVD method to produce polycrystalline graphene.
“We are starting to see large area sheet graphene being manufactured. While this method had been devised to produce graphene electrodes that would allow for lightweight, flexible solar devices and display screens, the technique can be adapted to create the material for a tether.” “We investigated three candidate materials for the study: Carbon nanotubes , Graphene, and Hexagonal Boron Nitride . hBN is another 2D material, nearly as strong as graphene and also a candidate tether material. The process for making 2D materials and CNTs is called the chemical vapor deposition method. The CVD process uses methane gas to make graphene, and this is an inexpensive feedstock and the basis for the current industrial manufacture.
At present, Nixon and his colleagues at the ISEC estimate that enough material could be generated to manufacture at tether for a cost of $18 billion – less than NASA’s 2022 budget of. Even more encouraging, they further estimate that with the right support and development, the price for producing single crystal 2D sheets of graphene could drop to as little as 1 cent per square meter , which would mean a tether could be built for $3.6 billion .
