This paper reports on the development and characterization of oxygen scavenging films made of poly(3-hydroxybutyrate) (PHB) containing palladium nanoparticles (PdNPs) prepared by electrospinning followed by annealing treatment at 160 °C. The PdNPs were modified with the intention to optimize their dispersion and distribution in PHB by means of two different surfactants permitted for food contact applications, i.e., hexadecyltrimethylammonium bromide (CTAB) and tetraethyl orthosilicate (TEOS). Analysis of the morphology and characterization of the chemical, thermal, mechanical, and water and limonene vapor barrier properties and the oxygen scavenging capacity of the various PHB materials were carried out. From the results, it was seen that a better dispersion and distribution was obtained using CTAB as the dispersing aid. As a result, the PHB/PdNP nanocomposites containing CTAB provided also the best oxygen scavenging performance. These films offer a significant potential as new active coating or interlayer systems for application in the design of novel active food packaging structures.

本文报道了由聚（3-羟基丁酸酯）（PHB）制成的吸氧薄膜的开发与表征，该薄膜含有通过静电纺丝制备并在160℃下进行退火处理的钯纳米颗粒（PdNPs）。为了优化PdNPs在PHB中的分散和分布，使用了两种食品接触应用中允许的不同表面活性剂，即十六烷基三甲基溴化铵（CTAB）和正硅酸四乙酯（TEOS）对PdNPs进行改性。对各种PHB材料的形态进行了分析，并对其化学、热、机械、水和柠檬烯蒸汽阻隔性能以及吸氧能力进行了表征。结果表明，使用CTAB作为分散助剂可获得更好的分散和分布。因此，含有CTAB的PHB/PdNP纳米复合材料也具有最佳的吸氧性能。这些薄膜作为新型活性涂层或中间层系统，在新型活性食品包装结构设计中的应用具有巨大潜力。
