英文摘要： The microwave absorbing materials is the most important in electromagnetic protection and military stealth. To resolve the problems of the traditional absoraing materials with great density, narrow absorption band, and complexity of the process, the design and synthesis of new type microwave absorbing materials becomes one of the most important fields in stealth science and technology.This project is aimed to diesgn new type absotption materials, which is beginning with the synthesis of Cu、Zn、Ni oxide/sulfide nanomaterials with low dimension and the flexible nanocomposites obtained by filling the polymer matrix with the synthesized nanomaterials. The project is focus on solving the technical problems of the absorbing materials with great density and narrow absorption band through electro-magnetic parameter regulation and wave-absorption properties by controlling the filler content of the nanomaterials, and further reveals the electro-magnetic parameters developing principles of flexible composites and enhanced microwave absorbing mechanism, in order to establish the method of regulating and controlling the electro-magnetic parameter of microwave-absorption nanocomposite, develop the flexible broadband microwave-absorption fundamental theory and design technique, realizes the basic theory innovation of the new type microwave-absorption nanomaterials with strong absorption、lightweight、broadband absorption、simple preparation process. This project can provide fundamental scientific basis for the design and properties regulation and control of flexible microwave-absorbtion nanomaterials, and broaden the application area of nanomaterials.
