    • Disclosed is a high-strength conductive film having excellent conductivity which can be applied in electronic devices, and which further reduces unevenness in conduction. The conductive film comprises modified fine cellulose having at least a carboxyl group and one type or two or more types of conductive substance. Further, the conductive film is formed by a process involving a step for oxidizing cellulose to prepare modified cellulose, a step for making finer the modified cellulose by dispersing the same in a dispersion medium to prepare modified fine cellulose, a step for mixing the modified fine cellulose and the conductive substance to prepare a dispersion liquid, and a step for drying the dispersion liquid to form a conductive film.
    • 本发明公开了一种具有优异导电性的高强度导电膜,其可应用于电子器件中,并进一步减少导电不均匀性。 导电膜包含具有至少一个羧基和一种或两种或更多种导电物质的改性微细纤维素。 此外,导电膜通过包括以下步骤的工艺形成:氧化纤维素以制备改性纤维素的步骤;通过将改性纤维素分散在分散介质中以制备改性微细纤维素以使改性纤维素更精细的步骤;将改性细纤维 纤维素和导电物质以制备分散液,以及干燥分散液以形成导电膜的步骤。
