To build a crystal PET film, we generated the coordinates of a small crystal sample by replicating the crystal packing information obtained by Tse and Mak 37 using Avogadro. The system comprised 72 PET polymer chains, arranged into 6 crystal layers such that each layer contained 12 units of hexameric chains. In doing so, we sought to model a thin PET crystal film while preserving the structural and spatial organization between polymer chains.
