| Abstract: | Reported values (0.2 MPa–7.0 GPa) of the interlayer shear strength (ISS) of graphite are very dispersed. The main challenge to obtain a reliable value of the ISS using conventional measuring methods was the unavailability of sufficiently large single crystalline graphite. Here we present a novel experimental method to measure the ISS, and obtain the value as ～0.14 GPa. Our result can serve as an important basis for understanding mechanical behavior of graphite or graphene-based materials. |
