Improvement of Hydrophilicity of Interconnected Porous Hydroxyapatite by Dielectric Barrier Discharge Plasma Treatment

Dielectric barrier discharge plasma treatment has been found to significantly improve hydrophilicity of the surfaces of interconnected porous calcium hydroxyapatite (IP-CHA), particularly that of wall surfaces of the internal pores. IP-CHA has been clinically used as a material for bone substitutes in bone tissue regeneration. Higher hydrophilicity of IP-CHA obtained in this method is expected to further increase the osteoconductivity of IP-CHA.
