Abstract

Filling crystalline gaps with small molecules can drive interfacial healing between anisotropic solids. Sufficient mobility from these fillers allows the process to happen at a low temperature of -56 °C. Mended bulk crystals show modulus leap from 4 to 12 GPa and hardness from 400 to 1000 MPa.

Keywords: healing; interfacial binding; low temperatures; metal-organic frameworks; welding.
