Fig. 1: GO schematics and mechanical responses.
From: Designing mechanically tough graphene oxide materials using deep reinforcement learning
a Schematic of GBP, where red atoms (66 in total) are hosts for functional groups while gray atoms are functional group-free atoms on which the tensile loading is exerted. Arrows show the loading direction. b Illustrations of hydroxyl and epoxide groups, where green and blue atoms are oxygen and hydrogen atoms, respectively. c Fracture of a low-toughness GO under tension. d Fracture of a high-toughness GO under tension. e Stress-strain curves of GOs in c and d.
