采用原子力显微镜（AFM）拟合力压痕曲线，研究了粒径分别为1.5 nm和3.0 nm的独立单层Pt纳米晶体的力学性能。结果表明，Pt膜的杨氏模量在1 ~ 10 GPa之间，断裂强度在1 ~ 30 MPa之间。
Mechanical properties of free-standing single layers of Pt nanocrystals with particle diameters of 1.5 nm and 3.0 nm were examined via AFM by fitting force–indentation curves. It showed that the Young's moduli of Pt membranes were in the range of 1–10 GPa and fracture strengths were in the range of 1–30 MPa.
