摘要: 本文以TEMPO氧化法制备的纳米纤维素为基材,结合纳米银线,经真空抽滤后得到纳米膜。将制得的纳米膜浸泡在氯化胆碱-尿素水溶液中,干燥后得到具有较好电学性能和机械性能的高透明纳米导电纸。制得的纳米导电纸的可见光透过率可达90%以上,最大拉伸形变为17%,比纯纳米纤维素纸的拉伸性能提高10倍以上。将制得的高透明纳米导电纸应用于纸基电容器,进一步拓宽了纸基导电材料在柔性电子器件中的应用范围。

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
