폴리비닐피롤리돈(PVP)과 은 양이온과의 상호작용을 상온 및 상압 조건에서 연구하였다. PVP와 PVP/Ag 복합체는 투과전자현미경(TEM), 자외선/가시선 흡수분광법, 라만분광법, 산소/이산화탄소 분석기를 통하여 관측하였다. 은 양이온은 PVP분자의 카르보닐기 산소원자에 있는 비공유전자쌍과 상호작용하여 안정한 PVP/Ag 복합체를 형성하는 것을 확인할 수 있었다.

The interaction between polyvinylpyrrolidone(PVP) and silver cation has been studied in water at room temperature and atmospheric pressure. The PVP and PVP/Ag composite was observed by transmission electron microscopy (TEM), UV-VIS absorption spectroscopy, Raman spectroscopy and oxygen/carbon dioxide analyzer. We identified silver cations interacting with nonbonding electrons of the oxygen atom in the carbonyl group of PVP. It was shown that PVP/Ag formed stable composites.
