摘要

摘要: 采用液-液界面沉积法，以甲苯和丙胺为溶剂，合成C₆₀-C₇₀富勒烯针状晶体固溶体。使用聚焦离子束扫描电子显微镜来测试其力学性能，C₆₀-C₇₀富勒烯针状晶体的拉伸强度为58~71 MPa，断裂韧性为1.1~1.3 MPa m^1/2。C₆₀-C₇₀富勒烯针状晶体拉伸强度显著高于C₆₀富勒烯针状晶体，其比强度略大于铝。通过富勒烯分子溶剂化可能改变C₆₀-C₇₀富勒烯针状晶体的塑性和断裂韧性。C₆₀-C₇₀富勒烯针状晶体有望用作电极、锚杆及电动给料机线等材料。

Abstract: Needle-like crystals consisting of a solid solution of C₆₀-C₇₀ fullerene were synthesized by a liquid-liquid interfacial precipitation method using toluene and 2-propanol as solvents. A machined crystal with a V-notch was placed in a focused ion beam scanning electron microscope where it was bent until fracture by pushing it with a molybdenum probe to measure its mechanical properties and its fracture surface was examined. The crystals had a tensile strength of 58-71 MPa, which is much higher than C₆₀ fullerene needle-like crystals and slightly larger than alumina, and a fracture toughness of 1.1-1.3 MPa m^1/2. Moreover, it is possible to change the plasticity and fracture toughness of the C₆₀-C₇₀ crystals by solvation of different numbers of fullerene molecules. The C₆₀-C₇₀ fullerene crystals have the potential for use as electrodes, anchors for brittle materials, and ductile wires to carry electricity.
