Abstract

The invention discloses a preparation method of high-strength transparent nanocellulose paper and belongs to the technical field of substrate materials. The preparation method takes phyllostachys edulis as a raw material and the phyllostachys edulis is subjected to bacterium fermentation to form a bacterium cellulose and nanocellulose compound; then the bacterium cellulose and nanocellulose compound is subjected to polyglutamic acid radiation to prepare a gel system, so that the film forming performance of the material is improved and the mechanical property of a nanocellulose paper forming material is effectively improved; compound cellulose and gel are compounded to form double-cross-linked network compound hydrogel; the structure of the gel is more compact; the toughness and the strength of the hydrogel are also increased and the strength of the material is improved; bacterium fermentation treatment is carried out and bacterium cellulose is prepared; the bacterium cellulose is composed of disaccharide repeating units connected by a beta-1,4-glycosidic bond so that a three-dimensional stereoscopic net-shaped structure is represented and the structural stability performance is effectively improved; meanwhile, a formed porous structure is used for filling a gap in a section so that the scattering of light is effectively reduced, a mutual effect of composite fibers is increasedand the light transparency and the optical performance of the material are improved.

Description

technical field [0001] The invention discloses a preparation method of high-strength transparent nano-cellulose paper, which belongs to the technical field of substrate materials. Background technique [0002] As an important part of flexible transparent conductive films, flexible organic transparent substrate materials have been used in flexible organic light-emitting diodes, transistors, solar cells, etc. It has been successfully applied in the field of electronic devices. At present, flexible organic transparent substrate materials mainly include polyimide, polyacrylic film, polypropylene diester, polycarbonate, polyethylene terephthalate, polyethylene terephthalate, polymethacrylate, etc. Organic synthetic polymer film materials such as esters, but most of the above-mentioned materials have disadvantages such as low processable temperature, high thermal expansion coefficient and poor printability during production and use, and these deficiencies hinder nanoscale electro...
