Abstract

The invention discloses a dandelion-like golden granule @ polyaniline nano composite material prepared by using a one-pot method and a preparation method and application of the dandelion-like golden granule @ polyaniline nano composite material. The method comprises the following steps: (1) uniformly dispersing a phenylamine monomer into an inorganic acid so as to obtain a phenylamine monomer dispersion; (b) putting a chloroauric acid solution as a gold source into the phenylamine monomer dispersion under a continuous stirring condition; and (c) performing a continuous stirring reaction till alight blue product is produced, further centrifuging, washing, and drying, thereby obtaining the dandelion-like golden granule @ polyaniline nano composite material. A conductive precious metal nanoparticle @ high-molecular polymer which is uniform in morphology and stable in structure and property is prepared by using the one-pot method, the method is simple and feasible, low in cost, gentle incondition and applicable to large-scale production, and as an electrode modification material, the obtained composite material is relatively good in conductivity and electrochemical activity, can be applied to catalytic detection on heavy metal pollutants in copper, and has the advantages of being high in sensitivity, good in recyclability, and the like.
