Description: The investigation of surface physicochemical and biological properties of polylactic acid and hydroxyapatite and composite materials based on them modified by Ag 1×1015 ion/cm2 and 1×1016 ion/cm2 40 keV ion implantation is presented. X-ray analysis reveals that ion implantation of the above mentioned materials leads to crystallite size and degree of crystallinity increase. The intensity of -С=О line is found by IR-spectroscopy to be decreased that is associated with surface layer carbonization processes of PLA during ion implantation. Silver ion introducing is established to enhance hydrophobic properties of the materials; this process is accompanied by free surface energy decreasing. It is shown that cell viability of non-implanted PLA is comparable with a control sample and ion implantation negatively affects to cell viability. The investigated materials can be promising for biomedical application.
