Absstract of: US2020283645A1

A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.
