| 제목 | Preparation Method of Antistatic Coating Consisted of Polymer Core-Metal Shell Particles |
| 초록 | Recently, the preparation of core-shell latexes comprising a dielectric solid sphere covered with a continuous metallic shell has attracted much attention.1 Core-shell latex particles are composite particles made of two different materials, one theoretically forms the core of the particles and the shell covers the core particle with the other material. Dependent upon the type of metal, they exhibited various properties such as magnetic, electrical, catalytic, and optical properties and, therefore, have extensive potential applications in the fields of medical science, biology, catalysts, coatings, and in many other fields. We were interested in the synthesis of composite particles consisted of a nonelectrical conductive core and an electrical conductive shell. The core and shell are made of poly(butyl acrylate-co-styrene) and nickel composite, respectively. When the conducting overlayer is continuous and uniform, it can be expected to obtain relatively high conductivities even at very low metal loading and also give more facile route to prepare conducting polymer dispersions having desired particle size.2 Several approaches have been proposed to form metallic layers on a dielectric core, and we applied the seeding/Electroless plating method.3 It has been successfully applied to form Ni shells on polymer core and the resistance of film made of the core-shell particles shows about 108 Ω/cm2. Even though it's resistance is higher than expected, but it is enough to act as antistatic material as known from Table 1. Table 1.
