Researchers from the Indian Institute of Science (IISc) developed a new shock absorbor made from graphene foam. The foam's load bearing capacity is very high, and when combined with PDMS it is very flexible and has an even higher load-bearing capacity - in fact six times higher than the bare graphene foam. The researchers say this can be used for mobile devices.
The GF-PDMS composite is reusable - it can withstand several cycles of operation without deformation. The material also features excellent thermal and electrical conductivity. The GF-PDMS is very light - its density is only 0.54 grams per cubic cm (iron has a density of 7.87 g/cm3, for example).
