Template-Based Synthesis of Nanoporous Hydroxyapatite

الملخص EN

Hydroxyapatite (HAp) particles, a potential starting material for bone substitutes, with nanopores were synthesized in the presence of cetyltrimethylammonium bromide (CTAB) and P123 as cationic and nonionic surfactants as the structuring units.

Effect of nonionic surfactant concentration on surface areas is also investigated.

Based on N2 adsorption-desorption isotherms investigation, surface area increased up to 50 m2/g by using P123 and 147 m2/g by using CTAB as porosity agent.

Pore structure remained even after the removal of surfactant and calcinations at 400°C.
