Abstract

In this study, we compared the effects of silica and gelatin in nano hydroxyapatite nHA composite with pure hydroxyapatite. We have synthesized hydrothermal nHA gelatin template and silica. They the obtained samples were investigated by x-ray diffraction XRD and Fourier transform infrared spectroscopy FT-IR . Scanning and transmission electron microscopy SEM was used for characterization of particle size and morp- hology of the samples. The percentage of elements in the prepared composite was determined using energy- dispersive x-ray spectroscopy EDS . We have identified that the use of gelatin and silica as a coating agent for nHA contributes to the increase in the size of the particles.

Nano-Hidroksiapatitin Boyut ve Özelliklerine Silika ve Doğal Polimerin Etkisi

Abstract

B u çalışmada, saf hidroksiapatit ile nano-hidroksiapatit nHA kompozit silika ve jelatinin etkileri kıyaslanmıştır. Hidrotermal nHA jelatin kalıp ve silika sentezlenmiştir. Elde edilen bu örnekler x-Işını kırınım XRD ve Fourier Transform Infrared Spektroskopisi FT-IR ile incelenmiştir. Örneklerin morfolojisi, partikül boyutu ve karakterizasyonu için taramalı ve geçirimli elektron mikroskobu SEM kullanılmıştır. Hazırlanan kompozit malzemedeki element yüzdesi enerji dağılımı X-ışını spekroskopisi kullanılarak belirlenmiştir. nHA için kaplama ajanı olarak kullanılan jelatin ve silikanın partikül boyutunun artmasına katkıda bulunduğu belirlenmiştir
