Abstract: A bacterial cellulose-based air filter mesh and use thereof are disclosed. The bacterial cellulose-based air filter mesh comprises a three-layer structure, in which a layer of a bacterial cellulose-based filter mesh is sandwiched by two layers of polymer fiber filter meshes; wherein the polymer fiber filter mesh is a mesh having a uniform grid size formed from polymer fibers by blended-yarn weaving; and the bacterial cellulose-based filter mesh is formed by in-situ synthesis of bacterial cellulose on a non-woven fabric through fermentation by bacteria. The bacterial cellulose-based air filter mesh has better particle filtering effect, better formaldehyde adsorption capacity, better antibacterial performance and good electrostatic capacity; and it can be used for producing gauze windows, air conditioning filters, air purification filters and the like, and has a wide range of applications.

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.
