Biodegradable biopolymers are currently being studied as replacements for their non-biodegradable counterparts used for food packaging today. In this regard Roberto Jorge Candal, María Lidia Herrera and team report on nanocomposite films containing sodium caseinate and glycerol reinforced with spherical or tubular TiO₂ nanoparticles. The geometry of the particles is seen to affect both their distribution in, and the properties of, the films. The scanning electron microscopy images shown reveal distinct structures for films with nanospheres or nanotubes. This variation in structure correlates with the different tensile properties measured for the films. DOI: 10.1002/bip.23531

目前正在研究可生物降解的生物聚合物，以替代当今用于食品包装的不可生物降解的对应物。在这方面，Roberto Jorge Candal、María Lidia Herrera 和团队报告了含有酪蛋白酸钠和甘油并用球形或管状 TiO ₂纳米粒子增强的纳米复合薄膜。颗粒的几何形状被认为会影响它们在薄膜中的分布和薄膜的特性。显示的扫描电子显微镜图像揭示了具有纳米球或纳米管的薄膜的不同结构。这种结构变化与薄膜的不同拉伸性能相关。DOI: 10.1002/bip.23531
