Abstract :
The paper is focused on the formation of Cadmium sulfide (CdS) nanoparticles in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. It is shown that PAA can be incorporated into the individual inverse microemulsion droplets. The PAA-filled microemulsion droplets can be successfully used as a template phase for the rice-like CdS nanoparticles formation. Formation of CdS at room temperature was confirmed by X-ray diffraction (XRD). Size and morphology of CdS samples were characterized using transmission electron microscopy (TEM).
