Abstract
Description
technical field
[0001] The invention relates to the field of cellulose treatment, in particular to a preparation method of nano-cellulose fiber dry powder. Background technique
[0002] Cellulose is a macromolecular polysaccharide composed of glucose. It is the most widely distributed and most abundant polysaccharide in nature. It is widely found in the metabolites of plants and some bacteria, and is a valuable natural renewable resource.
[0003] In the microstructure of cellulose fibers, there are crystalline regions where macromolecules are arranged and stacked in an orderly manner and amorphous regions where macromolecules are stacked disorderly. Among them, the physical and chemical properties of the crystalline region are more stable. Thus, smaller sized cellulosic materials, ie nanocellulose materials, are obtained through the destruction of the amorphous regions.
[0004] Cellulose materials at the nanoscale have special physical and chemical properties different fr...
