Embodiment 1

[0018] Example 1, 120g of tin tetrachloride pentahydrate and 14.3g of antimony trichloride were dissolved in 600ml of isopropanol, the above solution was poured into 1200ml of boiling water, neutralized to neutral with ammonia water, and kept on a low-temperature electric furnace for 70 -90°C for 1 hour, then let it cool down, filter it with a Buchner funnel covered with dense filter paper, then wash it ten times with pure water, transfer the obtained precipitate to a suitable container, add pure water to 800ml, Stir evenly, then put the above suspension into a 2L magnetically stirred high-temperature autoclave, heat up to 300-400°C after sealing, keep the pressure at 15-22Mpa, keep the temperature and pressure for 3-5 hours, stop heating and cool to room temperature , transfer the product to a container and let it stand for layering. The supernatant is poured into another container and heated to concentrate until viscous. The supernatant obtained by multiple synthesis can also...

Abstract

The invention discloses a transparent conduct nanometer dispersion and the method for preparing the same. The method employs simple process of hydrothermal synthesis and final treatment; final treatment employs grinding, ultrasonication, and high-speed centrifugation, and employs no auxiliary agent. The product is characterized by high purity, good transparency and conductivity, stable storage, no aggregation and sedimentation. The invention provides fine raw material for researching structure, synthetic mechanism and water-dispersible mechanism of stalline nanometer material.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing transparent nanocrystalline conductive functional materials, in particular to the application of a hydrothermal synthesis method to manufacture a long-term stable high-solid transparent conductive nanocrystalline water dispersion without additives and a preparation method thereof. Background technique: [0002] At present, common conductive materials such as metal and graphite are opaque materials. Modern high-tech technology requires a large number of new materials that are both transparent and conductive. At present, there are antimony trioxide, tin dioxide (ATO) and Indium and tin dioxide (ITO) transparent conductive materials, these materials often contain impurities, large particle diameter, low solid content, unstable during storage, easy to condense and settle, and are not easy to apply to technical fields with special requirements; in order to solve these problems, People have also ...
