Template synthesis based on bacterial cellulose / 中国组织工程研究

ABSTRACT

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.
