Behaviour of Monolayers of 4-methylbenzenethiol Encapsulated Gold Nanoparticles and two Kinds of Poly(etyleneoxide) Derivatives on Water Surface

Abstract

In this study monolayers of poly(ethyleneoxide) derivatives with gold thiol nanoparticles and lithium ions on water surface have been prepared. Surface pressure-area (Π-A) isotherms of these monolayers at the water surface has been studied. The area per molecule on water surface changes in size when gold thiol or lithium ions are added to monolayers of poly(ethyleneoxide) derivatives. Isotherm graphs of mixed monolayer using poly(ethyleneoxide) derivatives show a plateau region and a phase transition

Keywords

• PEO polymers, Surface isotherms, Lithium ions, nanoparticles

Abstract

Bu su yüzeyi üzerinde tek katlı tabakaları oluşturulmuştur. Bu tek katlı tabakaları su yüzeyi üzerindeki yüzey basınç – alan (Π-A) izotermleri çalışılmıştır. Poly(ethyleneoxide) türevine ait tek katlı tabakaya altın thiol nanoparçacıklar veya lityum iyonu eklendiğinde molekül başına düşen alan değişmektedir. Poly(ethyleneoxide) türevleri karıştırılarak hazırlanan tek katlı tabakanın izotherm grafiği plato bölgesi ve faz geçişi göstermektedir

Keywords

• PEO polimerleri, Yüzey izotermleri, Lityum iyonları, nanoparçacıklar
