Abstract

Rod-like hydroxyapatite (HAp)/poly (lactic acid) (PLLA) composite by the ionic interaction on the surface of the PLLA fiber was fabricated by the alkaline hydrolysis. The evaluation of the HAp/PLLA fabric was conducted by the scanning electron microscope (SEM), the methylene blue stain, the Fourier Transform Infrared spectroscopy and the X-ray photoemission spectroscopy. As a result, HAp adhered to the surface of the PLLA fabric uniformly. Cell adhesiveness of HAp/PLLA fabric composite was higher than that of an original PLLA fabric. Therefore, the HAp/PLLA fabric composite seemed to be useful as scaffold of the cell.
