Abstract

The invention provides a wide-spectrum extinction interference material and a preparation method thereof. The method comprises the following steps: respectively preparing a first solution and a second solution by utilizing a first container and a second container which are subjected to ultrasonic cleaning and drying treatment; obtaining a mixed solution of the first solution and the second solution, and performing aging treatment on the mixed solution to prepare a CoNi-MOFs precursor suspension; the CoNi-MOFs precursor turbid liquid is placed in a centrifugal machine to be subjected to centrifugal treatment, CoNi-MOFs precipitates with supernate removed are obtained, the CoNi-MOFs precipitates are placed in a vacuum drying box to be subjected to drying treatment, and CoNi-MOFs powder is obtained to serve as a CoNi-MOFs precursor; and the CoNi-MOFs precursor is placed in a tube furnace to be subjected to calcination treatment, and CoNi-MOFs-800 powder is obtained to serve as the wide-spectrum extinction interference material.

Description

technical field

[0001] The invention relates to the field of photothermal material preparation, in particular to a broad-spectrum extinction interference material and a preparation method thereof. Background technique

[0002] Precision-guided weapons have officially entered the stage of history since the Vietnam War. With the development of science and technology, it has become increasingly difficult for single-mode guided weapons to meet the needs of modern warfare. Therefore, dual-mode or even multi-mode guided weapons have become precision-guided weapons conventional way.

[0003] In order to counteract the existing photoelectric guidance means and photoelectric detection technology, smoke screen, as a cost-effective and fast passive interference method, plays a key role. It quickly releases a large amount of aerosol particles into the air to change the transmission characteristics of electromagnetic waves in the air to effectively interfere with photoelectric detection...
