Barrier Properties of Biodegradable Aliphatic–Aromatic Copolyesters (PBXT Series)
Front Cover: The free volume within materials is crucial for gas adsorption and diffusion. Size and distribution of internal fractional free volume significantly impact barrier performance. This study innovatively combines experiments and theoretical calculations to corroborate that methylene group growth in aliphatic units leads to decreased crystallinity, elevated free volume fraction, enhanced segment mobility, ultimately diminishing barrier properties. More details can be found in article 2400051 by Zhiyong Wei and co-workers.
