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

İnci Çapan

Öz


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.
