초록

무유화 에멀젼 공중합법을 이용하여 180∼200 nm의 지름을 가지는 단분산성 폴리(스티렌/디비닐벤젠/비닐 아세테이트) [poly(STco-DVB-co-VAc)] 고분자 나노입자를 합성하였으며, 제조된 단분산성 고분자 나노입자의 표면을 비누화반응을 통하여 개질하여 단분산성 폴리(스티렌/디비닐벤젠/비닐알코올) [poly(ST-co-DVB-co-VA)] 나노입자를 제조하였다. 합성된 입자를 반응염료와 반응시켜 적색과 청색 단분산성 폴리(스티렌/디비닐벤젠/비닐알코올) 나노입자를 제조하였으며, 입자의 형태, 분산성 및 표면전하를 전자현미경, 시차열분석기, UV/Vis 흡광기 및 제타 전하 측정장치를 이용하여 규명하였다.

Colored, electrophoretic polymer nanoparticles of poly (styrene-co-divinylbenzene-co-vinyl acetate)[poly(St-co-DVB-co-VAc)] were prepared by emulsifier-free emulsion copolymerization and reactive dyeing. The emulsifier-free emulsion polymerization of styrene, divinyl benzene and vinyl acetate was carried out at 70 ℃ for 20 hrs to obtain monodisperse polymer nanoparticles of poly(St-co-DVB-co-VAc) with an average diameter of 180∼200 nm. These nanoparticles were transformed into poly(styrene-co-divinylbenzene-co-vinyl alcohol) [poly(St-co-DVB-co-VA)] nanoparticles through the saponification reaction. The poly(St-co-DVB-co-VA) nanoparticles were treated with reactive dyes to obtain the colored, monodisperse electrophoretic nanoparticles, and their morphology and surface charge were characterized by scanning electron microscopy, differential scanning calorimetry, UV/Vis absorbance and zeta-potentiometry.

Keywords:poly(styrene-co-divinylbenzene-co-vinyl acetate);nanoparticles;saponification;emulsifier-free emulsion polymerization.
