Abstract

The invention discloses a multifunctional cellulose fiber based on graphene oxide / nano zinc oxide and a preparation method thereof. The method includes: impregnating cationic cellulose fiber in an anionic zinc oxide solution system and a cationic zinc oxide solution system in order for self-assembly, and finally wrapping the outermost layer of cellulose fiber with a layer of graphene oxide to obtain multifunctional cellulose fiber based on graphene oxide / nano zinc oxide. Nano zinc oxide undergoes layer-by-layer self-assembly by electrostatic attraction, endows cellulose fiber with excellent antibacterial, anti-ultraviolet, anti-wrinkle, anti-yellowing, washing resistance and other properties. Graphene oxide wrapping effectively improves the biosafety of inorganic nanomaterials. The invention applies electrostatic layer-by-layer self-assembly technology, nano-zinc oxide and graphene oxide in the textile field, is conducive to overcoming the current situation of single variety, low technical content and low added value of products in textile industry, and is of important significance for realizing transformation and upgrading and sustainable development of the textile industry.

Description

technical field [0001] The invention relates to a multifunctional cellulose fiber based on graphene oxide / nanometer zinc oxide, which belongs to the textile field. Background technique [0002] For a long time, cellulose has been the main industrial raw material for textile and papermaking. It has been paid more and more attention by people because of its renewability, biodegradability and cost advantages. , Functional chemicals and additives have shown good development prospects. Due to the reduction of arable land and the depletion of fossil resources such as oil and natural gas, the production of synthetic fibers will be more and more restricted. As a green, environmentally friendly and renewable resource, cellulose has obtained an unprecedented development opportunity (preparation of hyperbranched polymer and functional modification of cotton fiber [D]. Soochow University, 2009). [0003] Inorganic nanomaterials refer to materials with a size of 1-100nm. Compared with ...
