Study of spatial organisation of magnetic field directed gold-pickering-ferrofluid-nanoemulsion in spin coated film. [Dataset]

Abstract

Aim is to study the spatial organisation of the magnetically directed gold pickering ferrofluid emulsion via spin coating. The magnetically directed self-assembly manufacturing technique was successfully applied by combining the magnetic field and spin coating to form the thin film with nanostructure with array of chains of the gold Pickering ferrofluid (oil based) nanoemulsion dispersed in PVA aqueous solution. The manipulation of PVA carrier phase viscosity and spin speed allowed the control of the density of gold Pickering ferrofluid (oil based) nanoemulsion chain arrays. Spinning of the emulsion with low carrier phase viscosity at high spinning speed led to a narrower PEF-C-GM-FF emulsion chains density distribution. This potentially can reduce the cost of such antenna to increase the infrared absorption.
