COMPOSITE FILM FOR ELECTROMAGNETIC INTERFERENCE SHIELDING AND METHODS FOR FABRICATING THESE FILM

Abstract

The invention relates to a multifunctional electromagnetic shielding composite film based on cellulose nanofibrils, MXene Ti3C2TX nanosheets, and amine-functionalized carbon nanotubes covalently cross-linked with citric acid in the participation of adenosine triphosphate, which gives the film the ability to simultaneously shield against electromagnetic interference, conduct heat, be mechanically strong, flame-retardant, and have long-term oxidation resistance. The invention also relates to a method for fabricating this composite film.
