Preparation method of alpha-Fe2O3 conductive polyaniline composite material

Abstract

The invention provides a preparation method of an alpha-Fe2O3 conductive polyaniline composite material. The preparation method comprises the following steps: by using ferric chloride hexahydrate, sodium acetate, ethylene glycol and the like as main raw materials, synthesizing granular alpha-Fe2O3 by using a hydrothermal method, and compounding the granular alpha-Fe2O3 with conductive polyanilineto prepare the composite material with microwave and infrared wave-absorbing properties. An XRD performance test proves that the synthesized material has high crystallinity. The morphology characterization of the material is carried out through SEM, and a characterization result proves that the synthesized alpha-Fe2O3 is granular, and the alpha-Fe2O3 conductive polyaniline compound is of a core-shell structure. A wave-absorbing performance test is carried out on the compound through a vector network instrument, and it is proved that the compound has good wave-absorbing performance in microwaveand infrared bands and has high practical application value. The alpha-Fe2O3 conductive polyaniline composite material has good application prospects in the fields of microwave and infrared absorption materials, electromagnetic protection and the like.

Description

technical field [0001] The invention belongs to the field of preparation of microwave and infrared absorbing materials, in particular to an iron-nitrogen compound material with microwave and infrared absorbing properties and a preparation method thereof. Background technique [0002] Stealth technology refers to the use of various technical means to change one's own detectable signal characteristics to minimize the probability of detection by the opponent's detection system. According to the characteristics of the target to prevent being detected, the types of stealth technology can be divided into visible light stealth, infrared stealth, radar or microwave stealth, laser stealth and sound wave stealth, etc. According to relevant information, currently in the detection of combat aircraft and other targets, radar accounts for about 60%, infrared accounts for about 30%, and others account for about 10%. At present, there are three main methods of radar stealth for aircraft: o...
