Spin the products such as cloth mainly to be prepared by viscose process, there is stable chemical nature, bio-compatible, intensity height
Etc. characteristic, they packing, separate, the industrial circle such as weaving is all widely used.But, functional difference
Become the bottleneck problem of cellulosic material development.Cellulose and function nano particle composite quilt are proved a kind of
Important cellulose modified means.Recently, preparation and the performance study of cellulose/ZnO composite causes people
Extensive concern, but limited by cellulose dissolution difficulty, current its preparation method includes: 1) machinery is altogether
Mixed method, as Alejandro etc. uses mixing-pressure rolling equipment (750MPa) under elevated pressure conditions by cellulose
Pulp and ZnO powder are simply mixed and prepare cellulose/ZnO thin slice, and wherein the content of ZnO is
1.21～2.28wt%, and there is certain anti-microbial property.But, direct blending prepares cellulose/ZnO
Composite is higher to the requirement of equipment, is unfavorable for that extension produces.2) chemical method, the method is mainly passed through
Cellulose matrix is dipped in zinc salt precursor solution immersion, then obtains through sol-gel, mainly include water
Full-boiled process and solvent thermal two kinds, both need higher reaction temperature (90～150 DEG C) and longer response time
(3～20h)；Meanwhile, cellulose matrix need to repeatedly immerse precursor solution and carries out depositing to improve composite wood
The content of nano-ZnO in material.3) Electrospinning Method, prepares acetic acid by cellulose is performed the derivatization modification
Cellulose, is then together dissolved in organic solvent by itself and presoma zinc salt and carries out electrospinning, the nanometer material after electrospinning
Material finally prepares cellulose/ZnO nano hybridized film through washing, high-temperature process, but prepared by Electrospinning Method
The composite materials property obtained has much room for improvement.Additionally, cellulose/ZnO that said method prepares is multiple
Condensation material, nano-ZnO is mainly distributed on the outside of cellulose matrix, during as anti-biotic material, exists and is weak to
Washing and the short disadvantage of antibacterial time.
