MFC/NFC aerogel has water sensitivity, and it should be improved in strength in water before application. Chitosan was investigated as a MFC/NFC aerogel reinforcing agent in this paper. The reinforced aerogel showed slightly tighter structure and very good water stability and mechanical strength. FTIR disclosed the chemical bonds formed between chitosan and cellulose. Nanoparticles of silver (Ag-NPs) were loaded using the reinforced aerogel. The excellent Ag-NP monodistribution on the aerogel was expressed by TEM. Both chitosan-reinforced Ag-NPs loaded MFC aerogel and NFC aerogel and expressed great antibacterial activity, though reinforced MFC aerogel exhibited better properties, like higher BET, lighter density, more Ag-NP loading, and better distribution, than NFC aerogel in this research. Chitosan-reinforced MFC aerogel is a good potential substrate for nanoparticle loading and biocomposite making.

壳聚糖增强 MFC/NFC 气凝胶和抗菌性能

MFC/NFC气凝胶具有水敏感性，应用前应提高其在水中的强度。本文研究了壳聚糖作为 MFC/NFC 气凝胶增强剂。增强的气凝胶显示出稍微更紧密的结构和非常好的水稳定性和机械强度。FTIR 揭示了壳聚糖和纤维素之间形成的化学键。使用增强气凝胶加载银纳米颗粒 (Ag-NPs)。TEM 表示气凝胶上优异的 Ag-NP 单分布。壳聚糖增强的 Ag-NPs 负载 MFC 气凝胶和 NFC 气凝胶都表现出很强的抗菌活性，尽管增强的 MFC 气凝胶在本研究中表现出比 NFC 气凝胶更好的特性，如更高的 BET、更轻的密度、更多的 Ag-NP 负载和更好的分布.
