Abstract
Monodisperse polystyrene and its copolymer beads containing amine function were prepared for the electroless silver plating using reduction of silver alkylcarbamate complex in organic solvent. Soap-free emulsion polymerization was adopted for the polymerization of styrene, divinylbenzene(DVB), and 2-(N,N-dimethylamino)ethyl methacrylate (DAEMA) in the presence of poly(vinyl alcohol) in a water/methanol solvent. The resulting poly(styrene/DVB/DAEMA), containing 30/0∼1.5/0∼3 wt% in monomer composition, were found to be a sphere-type particle with diameter of 1 μm. Silver Agcoated polystyrene beads were prepared by in sito reduction of a silver 2-ethylhexylcarbamate (Ag-EHCB) complex solution with hydrazine without pretreatment of polystyrene beads. Robust Ag/polystyrene beads were analyzed by SEM, UV-visible spectrometer and XRD.

은 카바메이트 착체 화합물의 환원에 의한 무전해 도금법으로 은/폴리스티렌 비드를 제조하기 위하여 폴리스티렌 및 아민 관능기를 가지는 공중합체 비드를 제조하였다. 스티렌, divinylbenzene(DVB) 그리고 2-(N,N-dimethylamino) ethyl methacrylate(DAEMA) 단량체들을 poly(vinyl alcohol) 존재 하에서 물/메탄올을 용매로 사용하여 무유화중합을 진행하였다. 30/0∼1.5/0∼3 wt%의 단량체 조성을 가지는 poly(styrene/DVB/DAEMA) 비드는 구형으로 1 μm의 일정한 크기를 가지고 있었다. 아민 기능기를 가지는 폴리스티렌 비드의 무전해 도금은 비드의 전처리 없이 silver 2-ethylhexylcarbamate(Ag-EHCB) 복합체와 히드라진 환원제를 사용하여 메탄올 용액에서 진행하였다. 제조된 비드와 도금된 비드 표면의 형태를 SEM으로 관찰하였으며 은 도금된 비드를 분산시켜 자외선 흡수 변화 그리고 도금된 은의 성분을 XRD로 분석하였다.
