Abstract

The invention relates to a nanometer compound material with a repeatedly interpenetrating network structure and a production method of the nanometer compound material with the repeatedly interpenetrating network structure, and belongs to the field of production of compound materials. The nanometer compound material produced through the method of multiple dip-coating-drying-curing has multiple layers of sandwich structures and a net structure, wherein a nanometer material under each sandwich structure is regarded as a centralized function area, and the functional areas are connected with one another in a matrix by the net structure in a form of a net, so that under the circumstance of a low content, the functional advantages of the nanometer carbon material are exploited to the full, and meanwhile, the integrity and the connectivity of the matrix material are not undermined.

Description

technical field [0001] The invention relates to a multi-time interpenetrating network structure nanocomposite material and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] Nanomaterials are a new type of materials that are at the nanoscale in at least one dimension. Due to their nanoscale effects, they exhibit various excellent properties. Since their discovery in the 1970s, nanomaterials have been a focus in the field of material research. Adding nanomaterials as additives to polymers to form multifunctional composites is also an effective way to expand the properties and applications of polymer materials. The traditional preparation method of nano-composite materials is the blending method, that is, the nano-additives and polymer precursors are mixed and stirred to form composite materials. However, this method has the phenomenon that nano-fillers are difficult to disperse and are prone to vicious agglomeration, wh...
