摘要

封面：材料内部的自由体积对气体吸附和扩散至关重要。内部自由体积分数的大小和分布对阻隔性能有重大影响。本研究创新性地将实验与理论计算相结合，证实了脂肪族单元中亚甲基的增长会导致结晶度降低、自由体积分数升高、段流动性增强，最终降低阻隔性能。更多详情，请参阅由 Zhiyong Wei 及其合作者撰写的文章 2400051。

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.
