The mechanical and physical properties of the bionanocomposite films based on κ-carrageenan (KC)-gelatin (Ge) containing zinc oxide nanoparticles (ZnONPs) and gallic acid (GA) were optimized using the response surface method, and the optimum amounts of 11.19 wt% GA and 1.20 wt% ZnONPs were obtained. The results of XRD, SEM, and FT-IR tests showed the uniform distribution of the ZnONPs and GA in the film microstructure, and suitable interactions between biopolymers and these additives, which led to increasing the structural cohesion of the biopolymer matrix and improving the physical and mechanical properties of the KC-Ge-based bionanocomposite. In the films containing gallic acid and ZnONPs, an antimicrobial effect was not observed against ; however, the GA-loaded and optimum films show an antimicrobial effect against . The optimum film showed a higher inhibition effect against compared to the ampicillin- and gentamicin-loaded discs.
基于κ-卡拉胶（KC）-明胶（Ge）并含有氧化锌纳米颗粒（ZnONPs）和没食子酸（GA）的生物纳米复合膜的机械和物理性能通过响应面法进行了优化，获得了11.19 wt% GA和1.20 wt% ZnONPs的最佳用量。X射线衍射（XRD）、扫描电子显微镜（SEM）和傅里叶变换红外光谱（FT-IR）测试结果表明，ZnONPs和GA在膜微观结构中均匀分布，生物聚合物与这些添加剂之间存在适当的相互作用，这导致生物聚合物基质的结构凝聚力增加，并改善了基于KC-Ge的生物纳米复合材料的物理和机械性能。在含有没食子酸和ZnONPs的膜中，未观察到对……的抗菌效果；然而，负载GA的最佳膜对……显示出抗菌效果。与负载氨苄青霉素和庆大霉素的圆盘相比，最佳膜对……显示出更高的抑制效果。
