Investigation of Surface Properties of Eggshell based Kappa-Carrageenan-Polyvinyl Alcohol Nanobiocomposite Coated Low Alloyed Steel Foam

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 kappacarrageenan-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.
