Abstract
The present disclosure describes a method for preparing a paper nanocomposite, including: continuously providing a first suspension that includes lignocellulosic pulp fibers, cellulose nanofibrils, carbon nanotubes, and a cationic surfactant; continuously adding a second suspension to the first suspension to provide a slurry, the second suspension includes lignocellulosic pulp fibers, cellulose nanofibrils, carbon nanotubes, and an anionic surfactant; depositing the slurry comprising the first and second suspensions onto the substrate; and dewatering the slurry to form the paper nanocomposite.
Claims22
A method for preparing a paper nanocomposite, comprising:
- continuously providing a first liquid suspension comprising lignocellulosic pulp fibers, cellulose nanofibrils, carbon nanotubes, and a cationic surfactant;
- continuously adding a second liquid suspension to the first liquid suspension to provide a slurry, the second liquid suspension comprising lignocellulosic pulp fibers, cellulose nanofibrils, carbon nanotubes, and an anionic surfactant;
- filtering the slurry comprising the first and second liquid suspensions on a membrane to provide a filtered mat;
- and
- removing the liquid from the filtered mat to form the paper nanocomposite.
A paper nanocomposite, comprising lignocellulosic pulp fibers, cellulose nanofibrils, carbon nanotubes, an anionic surfactant, and a cationic surfactant.
