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.
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.
