Diamond

The modulus of diamond which is a form of carbon is approximately 1000 GPa. The modulus of a typical thermoplastic polymer which is primarily a long-chain molecule based on carbon chains is typically 1 - 2 GPa. Explain the difference in modulus values in terms of bonding in the material, the molecular structure and the arrangement of molecules in the solid material.



Any help is greatly appreciated.
