Cellulose is an organic compound with the formula (C₆H₁₀O₅)ₙ, a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%.

Biopolymer nano tunica fibrosa material capable of being biological degraded and absorbed, preparing method and uses of the same

The invention relates to compound millimicron fibrous membrane material of cellulose and cellulose matrix which can perform the biological degradation and the biological absorption and a preparation method thereof and an industry and medical purpose, and belongs to the biological macro-molecule non woven fabric material field which can perform the biological degradation and the biological absorption. Electrostatic spinning equipment is used to obtain the fibrous membrane material which can perform the biological degradation and the biological absorption, the weight of the cellulose is taken as basic reference, the component of the material comprises cellulose more than 0 and less than or equal to 100 weight parts, other biomacromolecule more than and equal to 0 and less than 100 weight parts, 0 to 10 weight parts of curative drug or 0 to 50 weight parts of inorganic catalyzer and / or 0 to 50 weight parts of inorganic strengthening agent. The material of the invention has good biological compatibility, biological degradation property and degradation absorptivity, and can be used for haemostasia material, wound cladding material, organization engineering supporting rack material, the transportation and release of medicine, artificial skin and blood vessel, and postoperation anti blocking material, beauty material and catalyzer carrier, filtering membrane and radiation protection material and so on.
