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。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.
