Moreover, graphene contains versatile properties, having the ability to hold its underlying size after stretching. Last decade, experts conducted atomic force microscopic (or AFM nanoindentation) tests for graphene membranes. This involved the material being concentrated over silicone dioxide holes.
These tests showed that graphene sheets, with a thickness in the range of 2 and 8 nanometres, had spring constants in the district of 1–5 n/m. Not only that, it showed results of Young’s modulus with 0.5 terrapascal. As of late, graphene’s in-plane Young’s modulus was estimated to be more than 1.0 TPa, still utilising AFM nanoindentation.
