Concentration of potassium ions in the body is important because of have an effect on the activity of the neurons in the brain. We synthesized reduced graphene oxide(rGO) with potassium ion capping agent. To solve the aqueous dispersion problems of graphene, low molecular weight material(18-crown-6) was linked on the reduced GO surface by the assembly approach. As a result rGO/18-crown-6 was well-dispersed in water. Furthermore, 18-crown-6 has a surface with a negative charge thus 18-crown-6 has the property that can be capped with a metal cation having a positive charge. Consequentially, graphene hybrid nanomaterials such as rGO/18-crown-6 would be expected to be applicated as a chemical sensor. 2016년 한국교통대학교 지원을 받아 수행하였음. |
