Modification of VO2 Nano-Powders by Stearic Acid and its Mechanism

摘要：

　　Stearic acid was applied to modify the VO2 nano-powders, and the influence of modified medium, dosage of modifier, amount of activator, time of modification on the surface modification effect were studied.The modification parameters such as modifying agent and the conditions were optimized.The changes of Surface groups, particle size and the lipophilic degree of the dispersion system of VO2 nano-powders before and after modified by the stearic acid were researched.The modification mechanism is chemical bonding, which is not physical adsorption.And then the stearic acid modified mechanism was established and applied to explain the the process of modification parameters optimization.The modification of VO2 nano-powders could be used in color nanometer energy-saving coating.
