The normalized bin distribution is in correspondence with the monotonically decreasing cumulative pore volume function 𝑉 𝑝 (𝑟), which is the volume of the pore space capable of being enclosed by spheres of radius r or smaller. The PSD is the derivation d𝑉 𝑝 (𝑟)/d𝑟. In this work we screen weaving structures, mostly by using the PoreBlazer code developed for structural characterization of porous materials. Furthermore, the crossing point displacement is calculated to describe the slide of the polymer chains. We defined the mass centre of 10 closest pairs of atoms between two intersecting molecular chains as the crossing point. The distance between the mass centre in IS and ES is regarded as crossing point displacement. The schematic of definition of crossing point is provided in Figure .
