Abstract

Silver particles were synthesized by chemical reduction with ionic liquids. Structure of silver particles were significantly affected by the cation parts of the ionic liquids. With increasing the length of the cation part, the smaller silver particles were formed regardless of the anion type. This is mainly attributed to the different stability of the ionic liquid structure formed by physical bond between cation parts. Among seven ionic liquids, [Omim][$PF_6$] was the most effective for synthesizing silver particles.

화학적 환원법에 이온성액체를 분산제로 사용하여 은 입자를 제조하였다. 이온성액체를 구성하는 양이온의 종류에 따라 제조된 은 입자는 다양한 구조를 가지는 것으로 관찰되었다. 이온성액체의 음이온에 상관없이 양이온의 알킬기의 길이가 길어질수록 은 입자가 작고 균일하게 형성되었다. 이는 이온성액체의 양이온이 길이에 따라 합성 중에 이온성액체들 간에 형성되는 구조체의 안정성에 차이를 보이기 때문이다. 조사된 7가지 이온성액체 중 [Omim][$PF_6$]가 은 입자 합성에 가장 효과적이었다.
