Abstract: In this thesis, nano-cellulose prepared by TEMPO oxidation and silver nanowires were used to prepare the nanofilm by the method of vacuum filtration. The prepared nanomembrane was soaked in the solution of choline chloride/urea aqueous. After drying, a highly transparent nano-conductive paper with good properties of electricity and mechanics was obtained. The obtained nano-conductive paper has a visible light transmittance of 90% or more, a maximum tensile strength about 17%, and a ten-fold increase in tensile properties over pure nanocellulose paper. The prepared highly transparent nano-conductive paper was applied to the paper-based capacitor, and it will broaden the application range of the paper-based conductive material in the flexible electronic devices.

Key words: nanocellulose, silver nanowires, conductivity, paper-based capacitors
