title: [HAP-glutin-acetic acid coating on degradable polyamides implant].
abstract: Hydroxyapatite (HAP) formation on the surface of the degradable polyamides implant by a coating technology was studied. A suspension of HAP-glutin-acetic acid was prepared and brushed on the surface of the implant at room temperature. Scanning electron microscopy (SEM), X-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FT-IR) were employed to study the composition and the microstructure of the coating. The results obtained indicate that the main composition of coating is crystal HAP, its structural formula is Ca10(PO4)6(OH)2. So the coating has bioactivity. The coating has also small pores, which can stimulate bone regrowth and adsorption of other bioactive materials or mediine. This technology is an effective method to improve medical performance of the polyamides implant.
