세균섬유소%모판%합성
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,片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.还可以利用细茼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 (BC) is a new kind of natural biological nano-materials which displays unique physical, chemical and mechanical properties. It has high bioactivity, good biocompatibility, and biodegradability. BC fiber has a nanoporous structure and certain nano-pore size distribution, and a large number of nanopores can be used as a "template". BC can be used as a template to synthesize nano-composite materials with three-dimensional network structure through biomimetic synthesis. BC can also be used as a template to stabilize and disperse the polymers which are easily assembled into a cluster or bundle in the ultra-fine fiber network structure. The BC template could be removed in order to change or optimize the properties of the composite material. The process can make use of the synergy between the BC template and inorganic materials to make a new type of hollow molecular sieve. It can synthesize a variety of nanoscale metal oxides with the hollow network. The present study of template svnthesis based on BC is introduced in this paper.
