Benefits of technology

This new technology allows for easy manufacturing of small metal structures with specific properties that cannot be achieved by current methods like casting or machining techniques. By adding an organizing agent called hydrofluorene (HFO) instead of just one molecule per unit weight, this process becomes more efficient than previous processes.

Problems solved by technology

This patented technical problem addressed in this patents relates to the development of efficient ways to prepare nanoparms made from metal oxides like Silver Oxide while also providing structural support material suitable for use in electronic devices. Previous techniques have been limited due to their limitations in producing these types of metallic particles without forming hilum shelf structures.

Abstract

The invention discloses a method for preparing a silver micron hollow frame structural material. The method comprises the following steps of firstly, preparing a AgNO3 aqueous solution at the room temperature, then, adding the appropriate quantity of a structure-directing agent HF and a reducing agent FeSO4 into the AgNO3 aqueous solution to form a mixed solution and furthermore, enabling the mixed solution mentioned above to stand in water bath of a certain temperature, keeping for a period of reaction time, and obtaining the silver micron hollow frame structural material after carrying out centrifugation, washing and drying on a product. The method for preparing the silver micron hollow frame structural material is simple, and with the method, large-scale production of the silver micronhollow frame structural material is realized.
