细菌纤维素是一种新型的天然纳米生物材料,它具有独特的物理、化学和机械性能,并且具有较高的生物活性、良好的生物相容性和生物可降解性。细菌纤维素本身是一种具有多孔性结构及一定孔径分布的高分子材料,其孔径在纳米数量级,大量的纳米级介孔可作为“模板”使用。以细菌纤维素为模板,可通过仿生合成路线合成三维网状结构的纳米级复合材料,也可以在超细微纤网络结构中稳定和分散易聚集成团或束的聚合物结构,并进一步将细菌纤维素模板移除,从而改变或优化所复合物质的性质。还可以利用细菌纤维素模板与无机物之间的协同作用制得具有内部通道的新型中空分子筛,从而合成各种纳米级的金属氧化物中孔网络结构。文章就目前以细菌纤维素为模板的合成研究进展进行初步探讨。
Bacterial cellulose is a new type of natural nanobiological material. It has unique physical, chemical and mechanical properties, and has high biological activity, good biocompatibility and biodegradability. Bacterial cellulose itself is a kind of macromolecular material with porous structure and certain pore size distribution. Its pore size is on the order of nanometers. A large number of nanometer mesopores can be used as template. Bacterial cellulose as a template can be synthesized by biomimetic synthetic three-dimensional network structure of nanocomposites, but also in the microfiber network structure can stabilize and disperse agglomeration or cluster polymer structure and further bacteria The cellulose template is removed, thereby changing or optimizing the properties of the complexed material. A new type of hollow molecular sieve with internal channels can also be obtained by synergism between bacterial cellulose template and inorganic materials to synthesize various nano-scale mesoporous metal oxide network structures. The article is currently on bacterial cellulose as a template for the synthesis of research progress.
