Sheets of graphene are used to reinforce the fabric of a portable emergency shelter. The shelter must withstand strong winds and be carried in a rucksack.
Suggest how graphene makes the shelter suitable for both parts of its use. Link each suggestion to graphene's structure or bonding.
122 exam-style questions on OCR GCSE Chemistry 2.3 Properties of materials, covering 2.3.1 Carbon bonding and the variety of organic compounds, 2.3.2 Diamond, graphite, fullerenes and graphene, 2.3.3 Bond strength, changes of state and predicting states, 2.3.4 Bulk properties and types of bonding, and 2.3.5 Nanoparticles: scale, surface area, uses and risks. Each one has a worked solution and a mark scheme showing where the marks go.
