Abstract

In this study, we developed a novel eggshell based kappa-carrageenan-polyvinyl alcohol nanobiocomposite coated low alloyed steel foam. The prepared nanobiocomposite was preferred as a coating function on the distribution of particles on the low alloyed steel foam. The scanning electron microscopy (SEM), stereo microscope, and fourier transform infrared spectroscopy (FT-IR) techniques were used to determine the chemical and surface properties of the nanobiocomposite and nanobiocomposite coated low alloyed steel foam. According to the characterization results, we observed that the nanobiocomposite coated low alloyed steel foam had a uniform controlled morphology. Furthermore, the mean surface roughness values of uncoated low alloyed steel foam and nanobiocomposite coated low alloyed steel foam were measured as 4.48 µm and 4.61 µm, respectively. Consequently, we showed that the nanobiocomposite was uniformly coated onto the surface of the micropore channel of the low alloyed steel foam. Based on these results, eggshell based kappa-carrageenan-polyvinyl alcohol nanobiocomposite is a promising nanomaterial for surface modification of the low alloyed steel foam with a controlled and homogeneously distributed surface feature in biomedical applications using a green approach.

Yumurta Kabuğu Bazlı Kappa-Karragenan-Polivinil Alkol Nanobiyokompozit Kaplı Düşük Alaşımlı Çelik Köpüğün Yüzey Özelliklerinin İncelenmesi

Abstract

Bu çalışmada, yeni bir yumurta kabuğu bazlı kappa-karagenan-polivinil alkol nanobiyokompozit kaplı düşük alaşımlı çelik köpük geliştirdik. Hazırlanan nanobiyokompozit, düşük alaşımlı çelik köpük üzerindeki partiküllerin dağılımında kaplama görevi ile tercih edilmiştir. Nanobiyokompozit ve nanobiyokompozit kaplı düşük alaşımlı çelik köpüğün kimyasal ve yüzey özelliklerini belirlemek için taramalı elektron mikroskobu (SEM), stereo mikroskop ve fourier dönüşümlü kızılötesi spektroskopisi (FT-IR) teknikleri kullanıldı. Karakterizasyon sonuçlarına göre, nanobiyokompozit kaplı düşük alaşımlı çelik köpüğün homojen bir morfolojiye sahip olduğunu gözlemledik. Ayrıca kaplanmamış düşük alaşımlı çelik köpüğün ve nanobiyokompozit kaplanmış düşük alaşımlı çelik köpüğün ortalama yüzey pürüzlülük değerleri sırasıyla 4.48 µm ve 4.61 µm olarak ölçülmüştür. Sonuç olarak, nanobiyokompozitin düşük alaşımlı çelik köpüğün gözenekli yapısının yüzeyi üzerine düzgün bir şekilde kaplandığını gösterdik. Bu sonuçlara dayanarak, yumurta kabuğu bazlı kappa-karagenan-polivinil alkol nanobiyokompozit, yeşil bir yaklaşım kullanılarak biyomedikal uygulamalarda kontrollü ve homojen olarak dağıtılmış bir yüzey özelliğine sahip düşük alaşımlı çelik köpüğün yüzey modifikasyonu için umut verici bir nanomalzemedir.
