Abstract
Electrospinning of fibres from cellulose spinning solutions is a typical example of bottom-up strategy to obtain nanocellulose structures. However, electrospinning of cellulose is challenging due to its limited solubility in typical aqueous and organic solvents. One approach to overcome this problem is direct electrospinning from spinning solutions of cellulose in ionic liquids1 or DMAc/LiCl2. These methods require electrospinning systems equipped with coagulating or water bath to ensure nanofiber precipitation and/or removal of salts like LiCl. Another possibility is to use cellulose derivatives that are easily soluble in common solvents, suitable for electrospinning. In case of cellulose esters it is possible to obtain cellulose nanofibers by hydrolytic treatment of electrospun nanofibers. Among cellulose derivatives, cellulose acetate (CA) has been widely utilised for preparation of electrospun nanofibers and converted into cellulose nanofibers by deacetylation or aqueous hydrolysis in sodium hydroxide solutions. Electrospun nanofibers can be modified with different (e .g bioactive) compounds or particles, like metallic nanoparticles to functionalise nanofibers. In this work, cellulose acetate and hydrolysed cellulose nanofibers prepared by electrospinning technique has been modified with silver nanoparticles. The obtained composites were characterised with use of spectroscopic (DRIFT-IR, Raman) and microscopic (AFM, SEM) techniques. They were also studied in terms of antimicrobial activity and catalytic reduction of 4-nitrophenol.
