| 제목 | Synthesis and Characterization of Poly(styrene-g-aniline) Copolymers: the Effects of Graft Density and Graft Length on Conductivity |
| 초록 | Conducting polymers have become a popular basic material for advanced applications including plastic batteries, electrochromic displays, and sensors. However, a few applications have been reported because conducting polymers based on polyaniline exhibit poor physical and mechanical properties and are not soluble in common solvents. To overcome these defects, several methods have been reported such as the modification of monomer, copolymerization, and the composite system by blending commodity polymers with conducting polymers. In this study, poly(styrene-g-aniline) (PS-g-PANI) was prepared by chemical synthesis method. The graft density and graft length were controlled to investigate their effects on conductivity. To obtain PS-g-PANI, poly(styrene-co-aminostyrene) (PSAMS) was synthesized by copolymerization of styrene and aminostyrene. The graft density was controlled by the amount of amnostyrene during the copolymerization. The graft length was controlled by the amount of oxidant and aniline during graft polymerization. The electrical and morphological characteristics of PS-g-PANI were investigated and compared with PS/PAN blends. |
