Abstract

The invention discloses a method for preparing nickel oxide nanocomposite from concentrated emulsion. The method comprises the following steps: 1 stirring and mixing nickel oxide and n-butyl oleate according to mass ratio of (1:4)-6 in a sealed condition; 2 washing the impregnated nickel oxide with ethanol and performing vacuum drying to constant weight; 3 stirring for dissolving deionized water and sodium dodecyl sulfate in a sealed condition to obtain an aqueous phase solution; 4 dispersing the nickel oxide and azobisisobutyronitrile into the oil phase of styrene and triallyl cyanurate through the ultrasonic dispersion; 5 slowly dripping the mixed solution obtained in the step 4 into the aqueous phase solution obtained in the step 3, continuously stirring after dripping to obtain the super-concentrated emulsion; 6 sealing and centrifuging the super-concentrated emulsion, reacting for 12-36 h in a constant-temperature water bath, and obtaining the nickel oxide nanocomposite through purification and vacuum drying. The nickel oxide nanocomposite prepared by the method is high coating rate, the reaction time is relatively short, and compatibility of the nickel oxide nanocomposite with a polymer in the application can be greatly improved.
