In this study, the magnetic particles were prepared through the chemical method, using the mixing a water solution of FeCl₂.4H₂O (1.0 M) and FeCl₃.6H₂O (1.5 M). Different weight percentage of magnetite (0%, 1% and 5%) and N-vinyl carbazole (NVC) were placed into 20 mL of NMP and chemical polymerization was performed by using AIBN as iniator at 70 ˚C for 24 h. These composites are characterized by methods such as SEM (Scanning Electron Microscopy, and UV-Vis (Ultraviolet-visible Spectroscopy). Thanks to these methods it can be inform about morphology and optical properties of the samples. Moreover, dielectric measurement of the samples have been done by impedance spectroscopy.

Poli (N-Vinil Karbazol) Magnetit Kompozitlerinin Hazırlanışı ve Elektro-optik Karakterizasyonu

Öz

Bu çalışmada manyetik partiküller, FeCl₂.4H₂O (1.0 M) ve FeCl₃.6H₂O (1.5 M) sulu çözeltisinin karıştırılması ile kimyasal yöntemle sentezlendi. Farklı ağırlık yüzdesine sahip magnetit (% 0, % 1 ve % 5) ve N-vinil karbazol, 20 mL NMP içine yerleştirilerek başlatıcı olarak AIBN kullanılarak 70 °C 'de 24 saat boyunca kimyasal polimerizasyon ile yapılmıştır. Bu kompozitler, SEM (Taramalı Elektron Mikroskobu) ve UV-Vis (UV-Görünür Bölge) spektroskopisi ile karakterize edilmiş olup, bu yöntemler sayesinde örneklerin morfolojik ve optik özellikleri hakkında bilgi edinilebilmektedir. Ayrıca, kompozitlerin dielektrik karakterizasyonları, empedans spektroskopisi ile araştırılmıştır.
