Abstract

The invention relates to a preparation method of a single side oxidized cellulose film. The preparation method is characterized by firstly preparing a porous cellulose film by adopting a phase transformation method, soaking the prepared cellulose film in a TEMPO / NaBr mixed solution with a certain pH (10-11), after carrying out treatment for 3-8 hours, immobilizing the cellulose film in molds in different thickness, preparing printing pulp with different NaClO contents to carry out printing treatment on one side of the cellulose film and carrying out washing treatment after reacting for a certain time, thus obtaining the single side oxidized cellulose film. The preparation method has the beneficial effects that the method is simple to operate, is mild in reaction conditions and high in reaction efficiency and is suitable for industrial production; obtainment of the single side oxidized cellulose functional film provides more possibility for functionalization application of the oxidized cellulose film; after being further processed, the single side oxidized cellulose film can be used in the fields of single side electric conduction, medical treatment, barrier films, and the like.

Description

technical field

[0001] The invention belongs to the technical field of preparation of a cellulose film, in particular to a method for preparing a single-sided oxidized cellulose film Background technique

[0002] Cellulose membrane has a series of excellent properties, such as highly hydrophilic, excellent permeability, pollution resistance, good physical and chemical resistance, high temperature resistance, high transparency and good physical and mechanical properties; Environmentally friendly and renewable; cellulose membranes have been widely used in osmosis technology, food processing, and medical applications in recent years.

[0003] The hydroxyl group on the cellulose macromolecular chain and the porous structure of the cellulose membrane make it possible to improve the shortcomings of the cellulose membrane such as poor water resistance and chemical corrosion resistance through chemical modification and loading technologies, and to further increase the added value of...
