Abstract

The invention relates to a Polypyrrole-PEDOT / Fe3O4 compound with the characteristic of microwave absorption and a preparation method of the Polypyrrole-PEDOT / Fe3O4 compound. The preparation method includes the steps of preparing white emulsion, adding ferrous chloride, adding ferric chloride, carrying out washing and drying, and the like. The absorption frequency band of the compound prepared according to the method can be adjusted by changing the thickness of the compound, the microwave absorption frequency band is obviously broadened, and good wave absorption performance is achieved. In the preparation process, electromagnetic parameters can be adjusted by changing temperature and the use number of oxidizing agents, and the method is of great significance in broadening the microwave absorption frequency band of the compound and preparing novel wave absorption materials.

Description

【Technical field】 [0001] The invention belongs to the technical field of novel wave-absorbing materials. More specifically, the present invention relates to a poly(pyrrole-dioxyethylenethiophene) / Fe 3 o 4 complexes, also involving poly(pyrrole-dioxyethylenethiophene) / Fe 3 o 4 Method for the preparation of the complex. 【Background technique】 [0002] Microwave material refers to a material that can absorb and attenuate incident electromagnetic waves, and convert its electromagnetic energy into heat energy to dissipate or make electromagnetic waves disappear due to interference. Absorbing materials were first used for military purposes and were called "stealth materials". Research on microwave materials in civilian applications such as television broadcasting, electronic devices, and microwave radiation protection has also received increasing attention. Absorbing materials are divided into traditional absorbing materials and new absorbing materials. New absorbing materia...
