Resumen:
Synthetic hydroxyapatite (HAp) was grown on the surface of cotton fibers obtained from a commercial pure cotton fabric (PCF). These fibers were previously functionalized using titanium isopropoxide, which is acting as a coupling agent between the fibers and the HAp. Several pieces of PCF were immersed in the titanium alkoxide to modify the primary hydroxyl groups of the cellulose, anchoring three labile OH's groups through a titanium atom. The FTIR spectra of cotton-HAp samples show the presence of HAp. The microanalysis of the cotton-HAp samples by EDS shows a Ca/P ratio of 1.75, which is slightly higher with respect to the stoichiometric value (1.67). It was found that HAp crystals were isotropically distributed on the surface.
