Çalışmada manyetik Fe3O4 nanopartikülleri birlikte çöktürme yöntemiyle sentezlendi. Sentezlenen nanopartiküllerin TEM ve partikül boyutlandırıcı ile boyutlarının 20 nm civarında olduğu ve XRD ile de yapılarının küre şeklinde olduğu belirlendi. VSM ile elde edilen manyetizasyon eğrisinden doygunluk manyetizasyon değeri (Ms) 53.28 emu/g olarak bulundu. Ardından Poli(vinil klorür) ile farklı yüzdelerde manyetik nanopartikül kullanılarak kompozitler hazırlandı. Hazırlanan kompozitlerin karekterizasyonu FT-IR spektrofotometresi ile yapıldı. TGA ve DSC ile termal analizleri yapıldı ve nanopartiküllerle hazırlanan kompozitlerde Tg değerlerinin saf PVC’ den daha yüksek olduğu görüldü. Elektriksel ölçüm sonuçlarından, MNP ilavesinin dielektrik sabitini düşürdüğü görüldü. Ayrıca AC iletkenliğinin artan frekansla artış göstermesine rağmen kompozitlerin iletkenliğinin saf PVC’ den daha düşük olduğu belirlenmiştir.

Synthesis, Investigation of Thermal and Electrical Properties Poly(Vinyl chloride)/Fe3O4 Magnetic Nanoparticle Composites

Öz

In this study, magnetic Fe3O4 nanoparticles were synthesized by co-precipitation. It was determined that the dimensions of the synthesized nanoparticles with TEM and Particle Sizer were around 20 nm and their structures were spherical by XRD. Saturation magnetization value (Ms) from the magnetizaton curve obtained by VSM was found as 53.28 emu/g. Then, composites were prepared using Poly (vinyl chloride) with different percentages of magnetic nanoparticles. The PVC/magnetic Fe3O4 nanoparticles were characterized by FT-IR spectrophotometer. Thermal analyzes were carried out by DSC and TGA, and Tg values of composites were found to be higher than pure PVC. From the electrical measurement results, it was observed that the addition of MNP reduced the dielectric constant. Additionally, although AC conductivity increases with increasing frequency, it is determined that the conductivity of composites is lower than pure PVC.
