Abstract
A nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite is described. The composite is obtained by absorbing nano-zinc oxide-supported bacterial cellulose microfibers on an alginate fiber spunlace non-woven fabric; the nano-zinc oxide is uniformly distributed on the surface of the bacterial cellulose microfibers. This composite has good biocompatibility, mechanical properties and water absorption properties, and has a great application prospect in biomedical fields, such as wound dressings, human body repair materials, tissue engineering materials, etc.
Claims17
A production method for a nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite comprising:
- dispersing a bacterial cellulose hydrogel in water to obtain a uniformly dispersed bacterial cellulose microfibril aqueous solution;
- adding sodium alginate and zinc salt to the bacterial cellulose microfibril aqueous solution, and then subjecting to a heating treatment, to obtain a nano-zinc oxide-supported bacterial cellulose microfibril aqueous solution;
- and
- immersing an alginate fiber spunlace non-woven fabric into the nano-zinc oxide-supported bacterial cellulose microfibril aqueous solution, and then freeze-drying, to obtain the nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite.
