For graphene we obtained 3.43 eV Ų per atom for the bending modulus, which is in good agreement with the literature. We found that MoS₂ is ∼11 times harder to bend than graphene, and has a bandgap variation of ∼1 eV as a function of curvature. Finally, we also used this strategy to study aluminosilicate nanotubes (imogolite) which, in contrast to graphene and MoS₂, present an energy minimum for a finite curvature radius. Roof tile shaped imogolite precursors turn out to be stable, and thus are expected to be created during imogolite synthesis, as predicted to occur by self-assembly theory.RSC advancesBending energy of 2D materials: graphene, MoS₂ and imogolite.PMC9077804211409481150718115080611302721160639Sofo JRogan JValdivia JAKiwi MGonzalez RIValencia FJMunoz FfalseBending energy of 2D materials: graphene, MoS₂ and imogolite.The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS₂), and imogolite.
