A dramatic improvement in the tensile strength of fullerene needle-like crystals

Abstract

Solid solutions of C60-C70 fullerene needle-like crystals were synthesized by liquidliquid interfacial precipitation using toluene and 2-propanol as solvents, which were bent until fracture using focused ion beam scanning electron microscope for the measurements of their mechanical properties. The C60-C70 fullerene needle-like crystals were found to show the tensile strength of 58−71 MPa and the fracture toughness of 1.1−1.3 MPa m 1 2 , where the tensile strength is much higher than that of the C60 fullerene needle-like crystals and the specific strength is slightly larger than that of alumina. Moreover, it is possible to change the plasticity and fracture toughness of the C60-C70 fullerene needle-like crystals by solvent. Thus, the C60-C70 fullerene needle-like crystals are suggested to be applied for materials such as electrodes, anchors as brittle materials, and electric feeder lines as ductile materials.

“…Furthermore, there exists an infinite number of possible variations, ranging from the most common to the most exotic, which makes the fullerene family exceptionally diverse and rich in various structural arrangements.
