Poli (N-Vinil Karbazol) Magnetit Kompozitlerinin Hazırlanışı ve Elektro-optik Karakterizasyonu
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.
Preparation and Electo-optical Characterization of Poly (N-Vinyl Carbazole) Magnetite Composites
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.
