A promising method for preparation of new functional nanocomposite materials based on bacterial cellulose and Au nanoparticles was proposed for the first time. The Au nanoparticles were obtained by biocompatible and environmentally friendly metal vapor synthesis. The structure and composition of the surface of composite films were studied by XPS, SEM, and IR spectroscopy. Gold nanoparticles were found to efficiently chemisorb nanofibrils of bacterial cellulose, which gave nanoparticles of approximately 25 nm in size with a “metal core–hydrocarbon shell” structure.

细菌纤维素与金属气相合成金纳米粒子相互作用的影响

首次提出了一种基于细菌纤维素和金纳米粒子的新型功能纳米复合材料的制备方法。Au纳米颗粒是通过生物相容性和环境友好的金属蒸气合成获得的。通过XPS、SEM和IR光谱研究了复合薄膜表面的结构和组成。金纳米粒子被发现可以有效地化学吸附细菌纤维素的纳米原纤维，从而得到大小约为 25 nm 的纳米粒子，具有“金属核 - 烃壳”结构。
