The biodegradable materials for the packaging sector have attracted much attention as they can effectively reduce the reliance on fossil fuel products. The introduction of two-dimensional layered fillers is readily available for packaging materials to minimize costs while enhancing performance. However, few studies have investigated the molecular structure changes of OMMT to further modulate the comprehensive performance of polyhydroxy butyrate (PHB) materials. To fill this gap, we innovatively modified the surfactant's structure to regulate the embedding and dispersion of montmorillonite (OMMT) and interfacial bonding with the substrate, thus further examining the material's antibacterial and degrading properties and discussing mechanisms for the first time. The prepared C18M7@PHB materials present enhanced tensile strength (180%) and high thermal stability, excellent antimicrobial properties compared to the unmodified one. Both the water vapor and oxygen permeabilities of composites have decreased by 87% and 55%, respectively. Moreover, it is found that the composites exhibit various degradation cycles mainly depending on active agent chain length. This work lays a solid foundation for multifunctional packaging materials based on fillers with two-dimensional layered structures.

使用表面活性剂结构调制策略的多功能蒙脱石/多羟基丁酸酯复合材料用于包装应用

用于包装领域的可生物降解材料因其可以有效减少对化石燃料产品的依赖而备受关注。二维层状填料的引入很容易用于包装材料，以最大限度地降低成本，同时提高性能。然而，很少有研究探讨OMMT分子结构的变化，以进一步调节聚羟基丁酸酯（PHB）材料的综合性能。为了填补这一空白，我们创新性地修改了表面活性剂的结构，以调节蒙脱石（OMMT）的嵌入和分散以及与基材的界面结合，从而进一步检验了材料的抗菌和降解性能并首次讨论了机理。与未改性的材料相比，所制备的C18M7@PHB材料具有增强的拉伸强度（180%）和高热稳定性以及优异的抗菌性能。复合材料的水蒸气和氧气渗透率分别下降了87%和55%。此外，发现复合材料表现出主要取决于活性剂链长度的各种降解循环。这项工作为基于二维层状结构填料的多功能包装材料奠定了坚实的基础。
