Abstract
Disclosed are a composite cellulose nanosheet with excellent transparency and strength and manufacturing method thereof. The manufacturing method of a composite cellulose nanosheet includes: preparing a dispersion including a cellulose nanofiber and a cellulose nanocrystal; preparing a nanosheet support with the dispersion; contacting the nanosheet support with a crosslinking agent; and placing the nanosheet support that has contacted the crosslinking agent between two sheets of barrier materials such as two sheets of glass plate.
