Free energy Fgel per a unit cell vs the extension ratio λ⊥. The free energy Fgel per a unit cell (rescaled by \(F_0( \equiv k_{\mathrm{B}}T\pi r_{{\mathrm{in}}}^{\mathrm{2}}h_0{\mathrm{/}}v_0)\)) is shown as a function of the extension ratio λ⊥ in the normal of the nanosheets for several values of the interaction parameter χ; a χ = 0.3, b 0.6132, and c 0.8. The values of parameters that are used for the calculations are s (=(rex − rin)/rin) = 0.2 and g0 = 1.0 × 10−3 (see Fig. 1 and Eq. (9) for the definition)
