Abstract

Cellulose acetate oleate (CAO)-reinforced poly(butylene adipate-co-terephthalate) (PBAT) composites were prepared by the solvent casting method. The influence of the addition of CAO on the mechanical property, thermal property, disintegration property, compatibility, and hydrophobicity of PBAT/CAO composites was investigated. Compared with PBAT, the tensile strength and Young’s modulus of PBAT/CAO with 4 wt% CAO were increased by 9.5% and 25.7%, and the disintegration rate was also increased by 2.8 times. The results of morphological property, contact angle, and water vapor transmission indicated that the PBAT/CAO composites had good interfacial interaction and compatibility, and the hydrophobicity was improved. PBAT/CAO was applied to strawberry preservation, and it showed excellent freshness retention performance. Moreover, a possible degradation pathway for PBAT/CAO composite was proposed. This work provided a way for the preparation and performance improvement of biodegradable materials, which is expected to be applied in the packaging field.

醋酸纤维素油酸酯增强聚（己二酸丁二醇酯-共对苯二甲酸酯）复合材料

采用溶剂浇铸法制备了醋酸纤维素油酸酯（CAO）增强聚（己二酸丁二醇酯-对苯二甲酸丁二醇酯）（PBAT）复合材料。研究了添加 CAO 对 PBAT/CAO 复合材料的力学性能、热性能、崩解性能、相容性和疏水性的影响。与 PBAT 相比，添加 4 wt% CAO 的 PBAT/CAO 的拉伸强度和杨氏模量分别提高了 9.5% 和 25.7%，崩解率也提高了 2.8 倍。形态学性质、接触角和水蒸气透过率的测定结果表明，PBAT/CAO 复合材料具有良好的界面相互作用和相容性，疏水性得到改善。将 PBAT/CAO 应用于草莓保鲜，显示出良好的保鲜性能。此外，还提出了 PBAT/CAO 复合材料可能的降解途径。这项工作为生物可降解材料的制备和性能改进提供了一条途径，有望应用于包装领域。

期刊介绍： e-Polymers is a strictly peer-reviewed scientific journal. The aim of e-Polymers is to publish pure and applied polymer-science-related original research articles, reviews, and feature articles. It includes synthetic methodologies, characterization, and processing techniques for polymer materials. Reports on interdisciplinary polymer science and on applications of polymers in all areas are welcome. The present Editors-in-Chief would like to thank the authors, the reviewers, the editorial staff, the advisory board, and the supporting organization that made e-Polymers a successful and sustainable scientific journal of the polymer community. The Editors of e-Polymers feel very much engaged to provide best publishing services at the highest possible level.
