Bu çalışmada,  sol-jel
yöntemi ile tetraetil ortosilikat (TEOS) ön başlatıcısı varlığında zirkonyum
fosfat  (ZrP) ve Poli (etilen oksit)
temelli ZrP/ PEO kompozit malzemesi üretilmiştir. Hazırlanan malzemenin yapısı
X-ışını difraksiyonu (XRD) ve Fourier transform IR spektroskopisi (FTIR)
yöntemleri ile incelenmiştir. Isısal özellikleri ise termal gravimetrik analiz
(TGA) ile incelenmiştir. TGA analizinde, sentezlenen malzemenin 300 °C’e kadar
kararlı olduğu bulunmuştur. Üretilen bu malzemenin maliyeti düşüktür, ayrıca
ısıtıldığında 100 °C’nin üzerindeki sıcaklıklarda 300 °C ye kadar bozulmaya
uğramamaktadır. 300 °C’ye kadar olan ısısal kararlılığı ve su tutma kabiliyeti
sayesinde ZrP/PEO kompozit malzemesi, ara sıcaklık yakıt pillerinde
kullanılabilme potansiyeline sahiptir.

Synthesis and characterization of zirconium phosphate and poly(ethylene oxide) based polymer composite

Öz

In this study, by using tetraethyl orthosilicate (TEOS) as
precursor, a composite material based on the zirkonium phosphate and poly (ethylene
oksit) (PEO) polymer (ZrP / PEO) has been prepared through the sol-gel method.
The characterisation of the obtained material has been carried out by using
flourer transform–infrared spectroscopy (FTIR) and X-ray diffraction (XRD)
methods. Thermal properties have been investigated with thermal gravimetric
analyzing (TGA). It has been founded that ZrP/PEO polymer composite material is
stable even up to 300 °C. Thanks to the thermal stability and water uptake
ability, ZrP/PEO polymer composite is the promising candidate to be used as a
medium temperature fuel-cell electrolyte material.
