The mechanical properties of 3D graphene are excellent in the following aspects:

First, high strength

Three-dimensional graphene can support a great multiple of its own weight, for example, some data show that it can support 40,000 times its own weight, and the structural morphology has not changed. At the same time, its compression modulus up to 100MPa, strength than the same weight of steel is 207 times greater. This shows that 3D graphene has extremely high mechanical strength, superior to all other aerogel materials.

High elasticity

Three-dimensional graphene has excellent elasticity, can be compressed to about 5% of its original size, and repeated compression (such as 1,000 times) is still able to restore its original form. This high elasticity makes three-dimensional graphene can maintain good recovery when subjected to external forces, and is not easy to be deformed.

Good mechanical stability

Three-dimensional graphene not only has high strength and high elasticity, but also has good mechanical stability. This means that when used for a long time or subjected to complex external forces, 3D graphene can maintain its structural integrity and stability, and is not easy to damage or failure.

Other Mechanical Properties

In addition to the above main mechanical properties, 3D graphene also has some other mechanical properties of interest. For example, its high specific surface area and high porosity provide fast transport channels for lithium ions and electrons, which contributes to its performance in applications such as electrochemical energy storage. In addition, the micro/nano structure of 3D graphene also allows it to display excellent superhydrophobic properties, which can provide 3D graphene with self-cleaning properties that are valuable in specific application scenarios.
