| Research Abstract |
The size and two-dimensional alignment controlled gold nano-particles were successively obtained by the reduction of gold ions in the nano-cylinders of amphiphilic di-block copolymer, PEO-b-PMA(Az), as nano-reactor vessels. In the micro phase separation structure of PEO-b-PMA(Az) thin film, PEO nano-cylinders aligned normal to the silicon wafer surface. By optimization of gold ion doping in PEO nano-cylinders and reduction conditions, the size controlled gold nano-particles were obtained at the upper site of PEO nano-cylinders. The diameter of gold nano-particles depended on the diameter of PEO cylinder used for the reduction reaction. The size of gold nano-particles were from 3.2 to 4 nm.
