Abstract

The invention relates to a method for preparing nanometer zinc oxide with micro-emulsion. According to the method, SDS/n-amyl alcohol-cyclohexane-NaOH micro-emulsion is dripped into a flask with SDS/n-amyl alcohol-cyclohexane-zinc nitrate in a constant-temperature tank of 30-70 DEG C by using a constant-pressure funnel and then mixed to obtain an ivory liquid; the ivory liquid is centrifuged to separate ultrafine particles from micro-emulsion, the ultrafine particles are sequentially washed with anhydrous alcohol for three times, then washed with water for three times and washed with anhydrous alcohol once during centrifuging, and finally are vacuum-dried at a temperature of 30 DEG C to obtain nanometer zinc oxide. According to the method, the DS/n-amyl alcohol-cyclohexane-zinc nitrate solution and the SDS/n-amyl alcohol-cyclohexane-NaOH micro-emulsion are used as raw materials, nanometer zinc oxide can be prepared in water-in-oil micro-emulsion water droplets by using the two materials, the operation is simple, the experimental conditions are mild, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of nanometer material preparation, and in particular relates to a method for preparing nanometer zinc oxide by microemulsion. Background technique [0002] Nano-ZnO is a material with many special properties such as non-migration, fluorescence, piezoelectricity, antibacterial and anti-inflammatory, and anti-ultraviolet. It is used in rubber, textiles, coatings, magnetic materials, gas sensors, image recording materials and other fields. It has a wide range of uses. The researches in the field of preparation and application of nano-ZnO at home and abroad are constantly being strengthened and deepened. The preparation of nano-ZnO is commonly used in the solid phase method - that is, the generation of ZnCO 3 The precursor is then pyrolyzed to generate nano-ZnO particles and the microemulsion method. Although these methods can obtain nano-ZnO particles, there are many preparation steps, the experimental condi...
