Biomineralization inspired process to produce polymer of desired need is a promising approach in the field of research. In the present work, the bacterial cellulose (BC) based nanocomposites with a 3D network were synthesized via a biological route by choosing the calcium salt of primary metabolites (calcium gluconate) as the carbon source. The BC based composites were characterized by employing with Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). During the preparation of nanocomposites, the calcium ions embedded on the cellulose fibrils were served as the nucleation center and calcium carbonate was deposited into BC network in the assistance of CO. The uniform distribution of embedded objects on the cellulose nanofibers between internal and external was achieved. The exploitation of organisms for inorganic growth, shape and self-assembling explores new opportunities to the design of original nanostructures.
受生物矿化启发的聚合物生产方法是研究领域中很有前途的一种方法。在本工作中,通过选择初级代谢物(葡萄糖酸钙)的钙盐作为碳源,通过生物途径合成了具有 3D 网络的细菌纤维素(BC)基纳米复合材料。通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)对 BC 基复合材料进行了表征。在纳米复合材料的制备过程中,嵌入在纤维素原纤维上的钙离子作为成核中心,在 CO 的辅助下,碳酸钙沉积到 BC 网络中。在纤维素纳米纤维内外实现了嵌入物的均匀分布。利用生物体进行无机生长、形状和自组装为原始纳米结构的设计探索了新的机会。
