Pd(Ⅱ) ink was synthesized by the hydrolysis of PdCl2 and NH4Cl, followed by treatment with a small amount of oxidant and stabilizing agent. The ink was stored in a refrigerator at 4℃. UV/vis measurements on dilute inks was measured at an interval of a week. TW-PI025 having very similar properties to KAPTON was used as PI film. For Ink jet printing, the surface of the PI film was treated with KOH solution. The best condition for printing was selected through measurements at various concentrations and treatment times. After printing with Pd ink following surface treatment, surface-bond palladium(Ⅱ) was reduced to metallic palladium by being immersed into NaBH₄ solution. The surface of Pd was plated with electroless copper plating solution at room temperature, resulting in appearance of copper lines. The morphology changes of the PI film before and after the surface treatment were investigated by FT-IR ATR and video microscope.

Palladium ink was synthesized by the hydrolysis of organometallic palladium or PdCl₂, followed by treatment with a small amount of oxidant and stabilizing agent. The ink was stored in a refrigerator at 4℃. UV/vis measurements on dilute inks was measured at an interval of a week. TW-PI025(TAPE WORLD) having very similar properties to KAPTON was used as PI film. For Ink jet printing, the surface of the PI film was treated with KOH solution. The best condition for printing was selected through measurements at various concentrations and treatment times. After printing with Pd ink following surface treatment, surface-bond palladium(Ⅱ) was reduced to metallic palladium by being immersed into NaBH₄ solution. The surface of Pd was plated with electro less copper plating solution at room temperature, resulting in appearance of copper lines. The morphology changes of the PI film before and after the surface treatment were investigated by FT-IR and video microscope.
용매열 합성법을 이용한 Bi₂Te₃ 나노튜브 합성에서의 반응 온도의 영향

The Bi₂Te₃ nanotubes could be prepared by a solvothermal reaction using the Te nanowires as template. The first step of synthesis is formation of the Te nanowires. Subsequently, alloying process is progressed to synthesize Bi₂Te₃. The Bi₂Te₃ nanotubes have an average diameter of about 200~300㎚, with a few micrometers of the length. Because morphology of the Te nanowires depends on the reaction temperature, the Bi₂Te₃ nanotubes fabricated finally are affected as well by the temperature conditions. The products were characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).
