This work provides an in-depth molecular structure design strategy for developing high-barrier polymer packaging films. A series of high-performance PPDThF copolyesters were prepared by utilizing the unique crystallization ability poly(propylene 2,5-thiophenedicarboxylate) (PPThF), as well a long-chain dicarboxylic acid, namely dodecanedioic acid (DA). The incorporation polyethylene-like polyester from DA into main chain polymers has been found to be random copolymerization, leading limited crystallizable sequence lengths. effects acids on thermal transition, aggregation structure, gas barrier properties, and optical properties copolyester investigated. results demonstrate that PPDThF-10 combines benefits conventional thermoplastics, like high strength (>30 MPa) modulus (>0.6 GPa), with mechanical physical characteristics chemically cross-linked rubber, including extensibility (ε = 730%) toughness (134 MJ/m–3). obtained so far thiophene-based can used in food applications.
