This is a comprehensive study reporting the fabrication of highly porous Gehlenite scaffold (Ca2Al2SiO7)—both with and without surface modification—for the first time. The sintering temperature of Gehlenite scaffolds was optimized. Next, the optimized Gehlenite scaffold was coated by polycaprolactone (PCL)-Forsterite (Mg2SiO4) nanocomposite to improve the scaffold’s brittleness and biological properties. 1375 °C was found to be the optimized sintering temperature by which the Gehlenite scaffold was consolidated. Different PCL and Forsterite concentrations were separately applied on the optimized scaffold to yield a complete nanocomposite coating without clogging the macroporous structure. …
