Özet

The electric and dielectric properties of ultrasound-assisted synthesized CdS nanocrystals-PVA mixture were studied in temperature range of 298 K to 498 K and frequency range from 200 Hz to 1 MHz. Scanning Electron Microscopy (SEM) shows that the morphology of CdS nanoclusters are formed in the form of mostly spherical nanoparicles with average size 10 nm. It was found that the nature of polarization processes in pure PVA and CdS-PVA nanocomposites are different. This is due to interfacial polarization in nanocompisites.
