A novel hybrid material with calcium and strontium release capability
The preparation of PDMS鈥揟EOS鈥揅aO hybrid materials by sol鈥揼el techniques has been widely described in
previous works. Calcium nitrate is the most common source of calcium used in these preparations.
However, to remove possible toxic nitrate by-products a thermal treatment is necessary at temperatures
above 500 1C, which leads to the degradation of the polymeric components of the hybrids. Strontium has
already shown some promising results in the therapeutic area, being used in cases of osteoporosis and low
bone density. In this study a new potential bioactive hybrid material was prepared, by sol鈥揼el techniques,
using calcium acetate as a novel calcium source. Also, for the first time, incorporation of strontium in a
PDMS鈥揟EOS hybrid system was evaluated. Samples were characterized before and after immersion in
Kokubo鈥檚 Simulated Body Fluid (SBF) by SEM, EDS, ICP and FT-IR spectroscopy
