Abstract

Effects of silver nanoparticles on the polymerization rate and morphology of poly(vinyl acetate) (PVAc)/silver microspheres prepared by suspension polymerization of VAc were investigated. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction and atomic absorption spectrometry were used to characterize the morphology and properties of the PVAc/silver microspheres. Due to the change of hydrophilicity of silver nanoparticles, appearance of the microspheres having golf ball-like convave surfaces was observed. Under controlled concentration of surfactant, PVAc/silver microspheres with various hollow structures were synthesized. In the case of silver nanoparticles modified by surfactant, the polymerization rate increased slightly. PVAc/silver microspheres with a conversion up to 80% were prepared via suspension polymerization.

현탁중합에 의한 폴리(비닐 아세테이트)((poly(vinyl acetate)(PVAc))/은 미세입자 제조시 사용된 은 나노입자가 중합속도 및 PVAc 미세입자의 형태에 미치는 영향을 고찰하였다. 주사전자현미경, 투과전자현미경, X선 회절, 원자흡수분광분석법을 이용하여 제조된 미세입자의 형태와 특성을 분석한 결과, 사용된 은 나노입자 표면의 친수성 정도와 계면활성제의 농도에 따라 미세입자의 표면이 골프공 표면처럼 오목해지거나 다양한 형태의 중공 구조를 가지는 PVAc/은 미세입자가 제조됨이 관찰되었다. 계면활성제로 개질된 은 나노입자를 이용하여 중합한 경우에 중합속도가 약간 증가하였으며, 80% 이상의 전환율을 가지는 PVAc/은 미세입자를 제조할 수 있었다.
