Abstract
(Purpose) A cellulose liquid dispersion is provided wherein a particle diameter peak of obtained fine cellulose can be controlled if mechanical treatment of oxidized cellulose is performed; and a molded body is also provided wherein the molded body is generated from the dispersion, has sufficient flexibility and gas bather characteristics. (Solution) A cellulose liquid dispersion is provided, wherein the cellulose liquid dispersion at least includes fine oxidized cellulose, wherein a volume-based particle size distribution of the fine oxidized cellulose exists in the range of 0.01 μm or more and 100 μm or less of volume-based particle diameter, and the two or more particle diameter peaks. Furthermore, a molded body is formed using the cellulose liquid dispersion.
