Mechanical properties of nanoporous graphene were evaluated by tensile and indentation tests. A high-precision Shimadzu EZ-SX instrument equipped with 1 and 500 N load cells was used to perform tensile tests of nanoporous graphene at a strain rate of 8.3 × 10−4 s−1. Tensile samples were cut into a dog bone shape with a gauge length of 6 mm, a width of 2 mm, and a thickness of 35 μm. Indentation experiments were carried out using a nano-/micro-indentation machine (DUH-W201S, Shimadzu) with a 20-μm spherical diamond tip. Nanoporous graphene samples with dimensions of 3 mm by 2 mm and a thickness of ~200 μm were prepared for compression testing. The total indentation depth was kept lower than 20 μm (10% of sample thickness) to avoid constraints from substrates. Hardness and elastic modulus were extracted from loading-unloading curves using the Field-Swain method (43).
