Abstract

Monodispersed particles of poly(styrene-co-4-vinylpyridine), poly(st-co-4vp) were prepared by soapless emulsion polymerization. Iron oxide was formed on the surface and inside of the poly(st-co-4vp) particles by thermal decompostion of iron pentacarbonyl. The obtained magnetic poly(st-co-4vp) particles was mondispersed and the average size was 250 nm. The magnetic poly(st-co-4vp) particles had 14% of iron oxide, which was identified as $Fe_3O_4$ by XRD. The magnetic poly(st-co-4vp) particles had superparamagnetism according to superconducting susceptometer (SQUID).

Styrene과 4-vinylpyridine의 공중합체(poly(st-co-4vp)) 입자를 무유화제 유화중합에 의해 합성하고 이 입자 내부에 iron pentacarbonyl을 침투시킨 후 열분해 시켜 입자의 표면과 내부에 산화철 나노입자를 갖는 자성 poly(st-co-4vp) 입자를 제조하였다. 얻어진 자성 poly(st-co-4vp) 입자의 크기와 분포, 열적 특성 및 자성 특성에 대해서 조사하였다. 자성 poly(st-co-4vp) 입자는 크기가 약 250 nm 정도로 매우 균일하였으며 약 14%의 산화철을 가졌다. 산화철은 XRD 시험에 의해 대부분 $Fe_3O_4$임이 확인되었으며 superconducting susceptometer (SQUID) 시험에 의해 자성 poly(st-co-4vp) 입자가 초상자성을 가짐을 확인하였다.
