초록
본 연구는 CO2 초임계 유체를 도금액과 혼합하여 PET 필름 위에 무전해 구리도금을 실시하였으며 초임계 유체의 혼용조건에 따른 그 도금 효과를 비교하였다. 이산화탄소 초임계 유체와 도금액의 부피비는 1:9가 최적이였으며 초임계 유체가 10 vol% 이상이 되면 혼합액의 분산성이 불량해져 층분리가 발생하였다. 구리 무전해도금은 25 ℃, 15 MPa 에서 수행된 구리막의 표면물성이 가장 균일하였다. 무전해 구리도금에서 도금액과 혼합시킨 초임계 유체의 역할은 단순히 용해도를 높여 주는 것이 아니라 도금막을 구성하는 구리입자를 1차 입자상태로 분산, 유지시킴을 확인하였다.
In this study, electroless plating of copper was performed on PET film by using the blend of supercritical CO2 and plating solution. The optimum volumetric ratio of supercritical fluid and plating solution was found to be 1:9 and dispersion property was poor at CO2 vol% langer than 10%. Electroless plating of copper was best at 25 ℃ and 15 MPa. Role of added supercritical CO2 is not to increase solubility but to disperse and maintain Cu-particles as the 1st particles.
