Selective nucleation of copper on fluorocarbon-resin surface by Nd:YAG laser-induced chemical reaction

레이저 유도 화학반응을 이용한 fluorocarbon 수지표면 위의 선택적 구리핵의 형성

Photochemical defluorination and substitution of fluorocarbon-resin surfaces using a pulsed Nd:YAG laser(266 nm) and copper-sulfate$(CuSO_4)$ aqueous solution were discussed. Interface of copper nuclei and fluorocabon-resin was chemically bonded through oxygen which was photodissociated from water in copper-sulfate aqueous solution under the laser irradiation. The reaction mechanism for chemical surface modification is discussed on the basis of x-ray photoelectron spectroscopy and atomic force microscope analyses.
