In summary, the composition and preparation method of the electrowetting material of the present invention, the domain density of the electromagnetic wave absorbing material is between ^u g / ml, Wei reduces the density of the wave absorbing material, and feeds the higher vocational «The requirement of __, the solution of the composition of the electromagnetic wave absorbing material of the city, her reduction is called mixing and lion; the preparation method of the composition of the Weibo absorbing material is simpler and more convenient than the conventional preparation method to reduce the preparation Time and cost. However, the above structure, characteristics and spirit of the above-mentioned Kawasaki, Na M. (4) tearing the scope of the profit are better than the ‘transfer of the Mei (4), and (4) she applied for the patent application within the scope of the patent application. Such changes and modifications should be included in this issue 200821349 ' [Simple description of the diagram] Η This is the flow chart of the daily heat and rain. The second figure is the map of the first reflection of the composition of the financial and Wei materials.
