Abstract

The invention discloses a super black material and a preparation method and application thereof, and belongs to the technical field of nanometer material preparation. The super black material is composed of a base copper nanometer cluster and a graphitized carbon layer supported on the surface thereof, and the super black material forms the core-shell structure and is composed of, by weight: 51.9%to 84.3% of the copper nanometer cluster and 15.7% to 48.1% of carbon. By using the copper 4-pentanedionate hydrate as an elementary material, the super black material and preparation method and application thereof coats the surface of the copper nanometer cluster with the graphitized carbon layer to form a unique core-shell structure. The obtained super black material is characterized by excellent light absorption, and has significant optical loss effect caused by surface effect and quantum effect. The absorption range of the copper nanometer cluster or the super-black carbon material is soextensive that the copper nanometer cluster or the super-black carbon material has good light absorption performance at the wavelength of 200-900 nm; and the preparation method of the super black material is easy to operate, low in cost of finished products and process cost and conducive to industrial production, and the process conditions are easy to control.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to an ultra-black material and its preparation method and application. Background technique [0002] Ultra-black material is a material with a reflectivity of less than 1% and an absorption rate of more than 99% for incident light within a certain range. In many optical devices, sensors, and solar energy converters, there is an urgent need for ultra-black materials in such devices because unnecessary reflection of incident light by the interface will have many adverse effects on performance. At the same time, due to the excellent stealth performance of the ultra-black material itself, it is also of great use in the military. [0003] In view of this, ultra-black materials have been extensively studied and applied in recent years. At present, the most outstanding performance is Vantablack developed by Surrey Nanosystems, which is mainly composed of vert...
