The bio-based nanocomposites are receiving great attention due to their large surface areas, nano-scale
dispersion, low-cost, biodegradable, and biocompatible nature. In this study, a green bio-based
nanocomposite as Kappa-Carrageenan/PVA/eggshell nanobiocomposite was synthesized by a
combination of microwave and ultrasound method. The synthesized nano eggshell based
nanobiocomposite and nanobiocomposite coated 17-4 PH stainless steel foam was characterized using
SEM, BET, and FTIR techniques. Furthermore, the 17-4 PH steel foams, used in various applications
such as the aerospace, chemical, and biomedical applications, were prepared using a space holder
method with powder metallurgy approach [4]. According to our results, we found that
nanobiocomposites exhibited an irregular shape with a diameter of 299.7 nm while the surface area was
109.201 m2/g. The novelty of this study was to prepare the novel nano eggshell based nanobiocomposite
coated 17-4 PH stainless steel foam using a dip coating method and investigated the surface tension
characteristics. The effect of the experimental parameters such as the mass fraction (2%, 5%, and 10%)
of eggshell, the mass fraction (2% - 5%) of surfactant (CTAB), pH (3-10), and temperature (20-50 oC)
on the surface tension of synthesized nanobiocomposites was investigated to optimize operating
parameters. Thus, the values of critical micelle concentration were determined for each the mass fraction
(2%, 5%, and 10%) of eggshell.
