Nanohydroxyapatite (n-HA)/nylon 6,6 composite scaffolds were produced by means of the salt-leaching/solvent casting technique. NaCl with a distinct range size was used with the aim of optimizing the pore network. Composite powders with different n-HA contents (40%, 60%) for scaffold fabrication were synthesized and tested. The composite scaffolds thus obtained were characterized for their microstructure, mechanical stability and strength, and bioactivity. The microstructure of the composite scaffolds possessed a well-developed interconnected porosity with approximate optimal pore size ranging from 200 to 500 μm, ideal for bone regeneration and vascularization. The mechanical properties of the composite scaffolds were evaluated by compressive strength and modulus tests, and the results confirmed their similarity to cortical bone. To characterize bioactivity, the composite scaffolds were immersed in simulated body fluid for different lengths of time and results monitored by scanning electron microscopy and energy dispersive X-ray microanalysis to determine formation of an apatite layer on the scaffold surface.

“…Briefly, n-HA slurry was prepared by a chemical coprecipitation method through aqueous solutions of the reactants according to Deng et al 33 The reactants used were of analytical grade. Then, with DMF replacing deionized water at around 153°C (boiling point of DMF), a nano-apatite slurry in DMF was obtained.…”

“…Thus, sintered HAP implants could only be successfully utilized in non-load bearing applications [6]. As a result, a great number of studies have been devoted to improve the mechanical properties of HAP biomaterials [4,7,8,9] either by adding reinforcing agents [10] or by trying to improve the sintering process [11,12].…”
