Description
Advancements in technology often rely on the development or enhancement of materials. Bacterial nanocellulose (BNC) has found diverse applications in fields such as biomedicine, ecology, and electronics, leading to increased interest in BNC-based composites1,2. Understanding the synthesis parameters that affect the crystal structure and morphology of these composites is crucial, as it directly impacts their functional properties. In this study, a composite material based on bacterial nanocellulose (BNC) and ferromagnetic particles Fe3O4 was investigated. BNC was obtained through the activity of bacteria during vinegar fermentation for 7 days in a suitable medium3,4. The research aimed to optimize the conditions for Fe3O4 precipitation by varying the standing time interval of BNC films in a neutral medium of distilled water after biosynthesis. Samples were allowed to stand for 7 days and 14 days before precipitation. The results showed that the samples standing for 14 days were not adequate, i.e., Fe3O4 precipitation was not achievable. The impact of different synthesis conditions was analyzed using SEM-EDS and FTIR methods.
