Abstract

The invention relates to a preparation method of a Co3O4 / PANI / MXene / PI electromagnetic shielding fabric. The preparation method comprises the steps: pretreating a PI fabric, and then carrying out plasma treatment; spraying MXene solution to the surface of the treated PI fabric for reaction; spraying Co3O4 / PANI nanowire solution on the obtained MXene / PI composite for reaction; treating the obtainedCo3O4 / PANI / MXene / PI composite in a PDMS (polydimethylsiloxane) solution. The preparation method is simple and has mild conditions, and the obtained electromagnetic shielding fabric has excellent conductivity and electromagnetic shielding performance.

Description

technical field [0001] The invention belongs to the field of preparation of flexible electromagnetic shielding materials, in particular to a Co 3 o 4 Preparation method of PANI / MXene / PI electromagnetic shielding fabric. Background technique [0002] With the rapid development of informatization and intelligence, electromagnetic waves, as an important carrier of information dissemination, have penetrated into all aspects of life, and electronic products have been more and more widely used in our national economy and various fields of our daily life, such as electronic communication , distance education, intelligent equipment, etc. are closely related to electromagnetic waves. Regardless of military or civilian use, as long as there is information generation, transmission, reception and processing, it must rely on electromagnetic waves as a carrier. But while electromagnetic waves bring us great convenience, electromagnetic radiation also brings us a lot of negative effects...
