Investigation of the dielectric properties of newly synthesized and well defined low molecular weight macrophotoinitiator polystyrene thin film

摘要

In this study, powder PI-PSt-N3 polystyrene structure was synthesized by thin film spin coating method. To do this, 2 mg powder PI-PSt-N3 polystyrene with 0.5% loss of balance was mixed with chloroform for magnetic at an ambient temperature T = 23 ℃ for8 hour (s). After coating, structural features the thin films were analyzed in an x-ray difractometer and dielectric electrical properties using a dielectric spectrometrer. The ellipsometer measurements of polystyrene films results show that the film thickness changed about 50 nm and 90 nm around and spectroscopic measurements of dielectric dielectric constant (ε') have shown about 7.
