Tuning the lattice thermal conductivity of bilayer penta-graphene by interlayer twisting

•For the first time, the effect of twisting on phonon transport of penta-sheet has been studied.•The in-plane lattice thermal conductivity of bilayer penta-graphene with a twist angle of 36.87° is reduced by 77.16% as compared to that of untwisted one.•The interlayer twisting not only can enhance three- and four-phonon scattering but also can uplift phonon coherence.
