Abstract

In recent years, PBAT, i.e., Poly(butylene adipate-co-terephthalate) stands out as a potential material for packaging due to its favorable characteristics. However, its high manufacturing costs, poor crystallization, and inadequate barrier properties have impeded its broader acceptance in the industry. To tackle these issues, our study introduces a novel approach by incorporating octadecylamine (ODA)-modified cellulose (OMCC) as an eco-friendly additive. OMCC not only enhances the dispersion of cellulose within the PBAT matrix but also prevents its re-agglomeration. The integration of OMCC into PBAT has led to its significant improvements in mechanical strength, UV resistance, compatibility, hydrophobicity, and effectively enhances gas barrier properties. This work provides a new and biodegradable composite film for food packaging.

改性纤维素/PBAT 薄膜的制备及其在食品保鲜中的应用

近年来，PBAT（即聚己二酸丁二醇酯-对苯二甲酸丁二酯）因其良好的特性而成为一种潜在的包装材料。然而，其制造成本高、结晶性差、阻隔性不足等问题阻碍了其在业界的广泛应用。为了解决这些问题，我们的研究引入了一种新方法，即加入十八胺（ODA）改性纤维素（OMCC）作为环保添加剂。OMCC 不仅能提高纤维素在 PBAT 基质中的分散性，还能防止纤维素再次团聚。在 PBAT 中加入 OMCC 后，PBAT 的机械强度、抗紫外线性能、兼容性和疏水性都得到了显著提高，并有效增强了气体阻隔性能。这项研究为食品包装提供了一种新型可生物降解的复合薄膜。

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
