In this study, chitosan and metal oxides, specifically copper oxide, zinc oxide, and a combination of both, were used to prepare blends. These blends were utilized to stabilize 40 wt % oil-in-water emulsions with 1 wt % blend at pH 4. The results obtained from scanning electron microscopy and transmission electron microscopy analyses revealed that the chitosan/zinc oxide (CS/ZnO) and chitosan/copper oxide/zinc oxide (CS/CuO/ZnO) combinations exhibited smooth, non-porous, and spherical surfaces in comparison to other systems. This behavior of CS/ZnO and CS/CuO/ZnO has improved the surface morphology of these blends.

壳聚糖/金属氧化物共混物对水包油乳液的流变性、稳定性和微观结构的影响

在这项研究中，使用壳聚糖和金属氧化物，特别是氧化铜、氧化锌以及两者的组合来制备混合物。这些共混物用于在 pH 4 下稳定 40 wt% 的水包油乳液，其中 1 wt% 的共混物在 pH 4 下稳定。扫描电子显微镜和透射电子显微镜分析获得的结果表明，壳聚糖/氧化锌 (CS/ZnO) 和壳聚糖与其他系统相比，氧化铜/氧化锌 (CS/CuO/ZnO) 组合表现出光滑、无孔和球形表面。 CS/ZnO 和 CS/CuO/ZnO 的这种行为改善了这些共混物的表面形态。
